Lammergeier or Bearded Vulture – One Cool Bird

Bartgeier Gypaetus barbatus front Richard BartzSome interesting links on the Lammergeier or Bearded Vulture that I found today starting with a link on BirdNote.  This vulture is not a scavenger of meat but of bones and wait until you see how they deal with the bones.  That’s one cool bird!

ABA Bird #981 – the Nutmeg Mannikin

Nutmeg Mannikin 1The September 7 post ABA Adds Nutmeg Mannikin, #981 by the ABA blogger Bill Pranty, announced the acceptance of species #981, the Nutmeg Mannikin, to the list of ABA countable species.  According to the California Bird Records Committee (CBRC) the Nutmeg Mannikin is an established species in certain regions of California which, in the end, was good enough for ABA acceptance.  It can now be counted but only in those regions.

When we lived in Southern California we knew of this bird’s existence through the short entry on a page of exotic finches near the back of our first edition copy of The Sibley Guide to Birds published in 2000.  We never actually saw one of these while we lived there (we left in 2005) but we did eventually see one on a vacation to the island of Kaua’I in 2012.  They have been long established on the Hawaiian Islands having been introduced in 1866 [Ref 2] and are on the AOU checklist which includes Hawai’i.  Even though most of the rest of the world recognizes this species by the name Scaly-breasted Munia, the ABA has the tradition of using the AOU name first if available.  Bill Pranty in his post hints that an AOU name change could eventually result in a change to the more widespread name that is also the name recognized by the International Ornithologists’ Union [Ref 4].

I tried to find out where the alternate name of Nutmeg Mannikin came from but have so far been unsuccessful.  All I have been able to discover is that in the pet trade the more common names are Nutmeg Mannikin or Spice Finch. If anyone knows the answer I would love to find out.

If you want more information on the Nutmeg Mannikin, take a look at Bill Pranty’s blog article.  It has lots more information and useful links.  I now have one more bird to look for on my next visit to Southern California.

Roger Tory Peterson

Yesterday, August 28, was the 105-th anniversary of the birth of Roger Tory Peterson one of the most influential naturalists of the 20-th century.  Born in 1908 in Jamestown New York, his first book, Field Guide to the Birds was published in 1934 when he was only 26, and helped make bird identification accessible to the general public.

The Roger Tory Peterson Institute (RTPI) was founded in Jamestown to continue his work.  Their website has a excellent short biography of RTP which highlights his accomplishments and shows just how important his work was to the environmental movement of the 20-th century.

UK’s Blogging Red Kites

Blogging Birds is the name of a web-site run by a group of researchers at the University of Aberdeen in Scotland in conjunction with members of the RSPB (Royal Society for the Protection of Birds). The site’s byline, The lives of red kites, told by computers, sums up what the site is all about.

Red Kites 5 (5939879892) The Red kite is a species of raptor that, according to the web site, was once widespread in the UK and, after having been almost extirpated (down to 10 breeding pairs in Wales in the 1940’s) is making something of a comeback.

What the researchers have done is to fit several birds with satellite transmitters that provide accurate positions for the birds several times per day. These can be plotted on a map which anyone can see online. So far, pretty cool, but there’s more!

In addition to the geo-tracking, the researchers have linked in information from other databases that tell them about the areas visited by the birds. They know if an area is urban or rural and, based on land use information, can guess at how a bird might be feeding itself. They also know when a kite is near its home turf or if it is exploring far outside its normal range. Finally, if their path crosses that of one of the other tracked kites, they have information about their possible interactions with others of their species.

The final piece that let’s them create blog postings on behalf of the kites is something called Natural Language Generation which synthesizes all the data with known kite behaviour and spits out the weekly computer generated postings that anyone can see. Looking at the web-site today I see that they have four blogs on tap for the kites: Wyvis, Moray, Millie and Ussie. There appear to be other tracked kites as well with one of them, Beauly, mentioned in Millie‘s latest post for the week of August 12 to 18.

It will be interesting to follow one or more of the kites over longer periods of time. Perhaps these blogs can help to reduce the animosity that once almost led to the Red Kite’s extirpation from the British Isles.

Notes

Of the three most common North American kites, the Red Kite is closest taxonomically to the Mississippi Kite of the south-eastern US sharing the same sub-family (Milvinae) but different genera. The White-tailed and Swallow-tailed Kites are both from a different sub-family (Elaninae). All of these kites are from the family Accipitridae of diurnal birds of prey.

The related species of Black Kite is sometimes seen in England, usually during migration. Both it and the Red Kite are from the same genus Milvus and have been known to hybridize.

Birding Song Parodies by Young Birders

A couple of mornings ago, I came across the following ABA blog post by ABA president Jeff Gordon: Ladies and Gentlemen, LIVE from Camp Avocet…Pish & Twitch!!!. For anyone who likes birding and musical parodies it’s worth a listen (I missed breakfast and was almost late for a dentist appointment trying to make it through the YouTube links).

In a nutshell: Camp Avocet is an ABA run summer camp for young birders and Pish & Twitch is a musical duo newly formed by two of the campers Caleb and Brendan. Following a long tradition in song parody, they took well-known tunes and replaced the lyrics to poke fun at, in this case, birding and birders. Five songs were recorded and can be found on YouTube, through the links in Jeff’s article.

The first three songs (in posted order) used contemporary tunes the only one of which I recognized was their second song “Moves Like Jaeger” which was obviously a parody of the Maroon 5 and Christina Aguilera hit “Moves Like Jagger”. The other two tunes were lifers for me once I made identifications with the help of my phone’s SoundHound app.  The first song “Chase Me Maybe” about going after rare bird sightings, covered “Call Me Maybe” by Carly Rae Japsen and the third tune, about night-time bird call identification, “Flight Calls”, used the melody (if you can call it that) from “Thrift Shop” by “Party DJ Rockerz”.

The final two songs were based on well known hits from my own youth. The first of these was “Migrants Go By” sung to the Don Mclean hit “American Pie”. Impressively, they covered the 8-plus-minute long version and not one of the shorter radio-friendly variants. And finally, the song, “Bill Stewart”, clearly aimed at all of the camp leaders, was sung to the Billy Joel hit “Piano Man”.

It wasn’t what you might call a ‘tight’ performance as they had obviously bitten off more than they had time to practice for but that did not seem to detract from the energy in the room.  Besides, the hard part of a parody is crafting the lyrics and there they did some excellent work.

If you are a part or or even just familiar with birding culture then you will probably enjoy listening to Pish and Twitch.

Sandhill Crane Adventure at the Reifel Bird Sanctuary

Squawking Sandhill Crane(for J & C – You know who you are!)

Last Sunday I went to the George C. Reifel Migratory Bird Sanctuary in Delta BC.  I spent about 3 hours wandering around watching birds and taking pictures of anything interesting. In the end, however, about two-thirds of the pictures were of Sandhill Cranes.

It wasn’t that there were hundreds or thousands of them and almost nothing else – in fact, there were only about a dozen or so I never saw more than 4 in a group. No, the real reasons that I took so many Sandhill Crane pictures were that:

  • Several of the cranes were relatively tame and did not fly away when I approached.
  • It is a lot easier to take pictures of a crane than a chickadee.
  • The cranes were in my way, blocking the path in the direction that I was going.

One quick side comment:  During my visit I watched people feeding both cranes and chickadees right out of their hand (the chickadee had to land on the hand first which – obviously – the crane did not do).  Personally, I would feel safer feeding the chickadee. Up close, a crane bill looks like it can deliver a pretty hard poke.

Anyways, when I showed up at the sanctuary, I didn’t really expect to see Sandhill Cranes at all. I had been there a week earlier with a photography group that I recently joined and we had only heard a single crane calling (which we didn’t even get to see). Imagine my surprise when, walking one of the paths through the middle of the sanctuary, I ran into a group of cranes along the path ahead of me. Here are two of them:
Sandhill Cranes

These two were but half of a posse of 4 adult birds blocking the path. Here are 3 of them checking me out. You can just see the fourth hidden behind the foliage on the right.
Sandhill Cranes

I must not have been very threatening as they proceeded to turn their backs and head back along the path in the direction that I was hoping to go (though I would have preferred a less leisurely pace).
Sandhill Cranes

I finally made it around the bend in the path.

Hey, nice ‘digs’!

Apparently they were squatting in one of the prettiest parts of the sanctuary.
Sandhill Cranes

All I needed to do was get past these three who did not appear to be paying me much attention.  How about along the edge of the pond?
Sandhill Cranes

Hey! You’re not cranes! This story is supposed to be about cranes!  Still, pretty cool. It was two mallards, one leucistic (missing some pigment making them look white – not albinism though).
Leucistic Mallard ?

Anyways, back to sneaking past the cranes…

Drat! Spotted!

They may seem tame but there’s no point in getting too close. Time to backtrack and go around.

I turned back and went up the North edge of the sanctuary past the viewing tower. I watched some Dowitchers and Yellowlegs on my way by one of the larger ponds and then headed South briefly spotting my nemesis bird, the Marsh Wren, who was no doubt sticking his tongue out at me as he dove into the long grass.

I had walked most of the way down the West edge of the sanctuary when I encountered 2 more cranes, even friendlier than the first 4. The crane on the left was cleaning up a spot on the ground where I suspect someone had dropped a handful of crane-food – some kind of coarse seed mixture. The crane on the right was keeping an eye out – whether for threats or treats was unclear.
Cranes blocking the path

What was obvious was that they were quite tame allowing me to get close – really close.

This must be a good snacking spot. At one point a trio of people showed up and one of them offered the cranes a handful of something – more crane kibble probably – that they seemed to like a lot as they took it straight out of the person’s hand.

I imagined the crane thinking: “A teensy nip, he drops the goods and no-one gets hurt” (or is that “hoit”?).
Cleaning up after messy humans

So maybe it was an ambush spot too! There we were, blocked by a pair of ruthless sandhills forcing all passers-by to empty their pockets.

There was no way that I was giving up my bag of cashews.

Lucky for me, there was a distraction – a group of three sandhills flew overhead heading out into the marsh that separated the sanctuary from the open water of the Strait of Georgia.
Sandhill Cranes in Flight

A short time later, a second group of 4 flying cranes appeared. This group, however, let out a group call as they passed overhead. I must say, these are pretty loud birds with quite a bit of lung-power behind their calls. It was clearly some kind of message because the two birds not 10 feet ahead squawked in return.
Crane Duet 3/5

They got in a couple of rounds of noisy calls before the flying group were out of range.  It was an award winning performance.

Envelope please!

… and the winner of the Squawky goes to …
Crane Calling

The squawking was over and the people with crane-kibble in their pockets had left.  I finally slipped by and headed for the exit and that was the end of my Sandhill Crane Adventure.

More on Sandhill Cranes at the Sanctuary

The Sanctuary has resident Sandhill Cranes that live there year round (and has had for about 30 years).  While other groups of cranes will come and go, when the breeding season comes around only the resident pair will remain to nest and try to raise a family.  Last year (2012) they had one chick that unfortunately died.

The sanctuary has lots more pictures and information on their Sandhill Cranes page.

Glorious Twelfth or a Hen Harrier’s Bad Day

For some, August 12 is a special day in Great Britain. It is the start of the hunting season for the Red Grouse, king of the game birds, as fixed by parliament in the Game Act of 1773. The day proudly bears the title of the Glorious Twelfth and, unless the supply of birds runs out, the hunt continues until December 10 (November 30 in Northern Ireland).

Red Grouse – King of the Game Birds

What gives the Red Grouse its royal title?

First, it is the only game bird that is endemic to the British Isles and can be found throughout Ireland, Scotland, Wales and Northern England with some territory extending into England’s southwest.

Second, a flushed Red Grouse bird can reach speeds of over 70 mph (I have seen 80 and even 90 mph used in different sources). The greater the speed, the greater the challenge to the hunter, particularly during the pinnacle of game hunting – the driven hunt.

In the driven game hunt, a row of 8 to 10 guns (the hunters) line up a certain distance apart, each in their own butt or stone box which provides some shelter, protection and concealment. The guns face in the direction from where a volley of Red Grouse, flushed by a line of beaters, will appear. The gun is now confronted by some number of birds, between a pigeon and a mallard in size (a typical weight is 600 g), coming at them usually low to the ground and fast enough to break the speed limit on any public road in Great Britain or Canada. The hunter’s task is to shoot as many of them as he can without injuring either beater or neighbouring gun. In principal, the hunt can continue in this manner all day long. Some historic hunts have seen enormous bags consisting of several thousand birds. There are reports of a single hunter shooting over 1000 birds in a single day. In today’s hunt, bags of 50 to 200 brace (1 brace = 2 birds) appear to be more typical for a line of 8 to 10 shooters during a day of driven hunting.

[A fascinating historic account of a driven hunt during the late Victorian Era can be found in the section on Grouse and Partridge Driving in the 1903 book Horses, Guns and Dogs.]

The hunters that come to the grouse moorlands for the challenge of shooting at these feathered-rockets make an important contribution to the economic activity of many communities where the appropriate conditions exist. The traditional grouse hunt that attracts the hunters has evolved a sophisticated management system that has the primary goal of maximizing the number of Red Grouse that are available for the shoot. There is much tradition and etiquette that comes with the today’s driven hunt, most of which are still run from private estates.

This year, the cost to participate in a driven hunt runs in the neighbourhood of £130 per brace with the expectation of a full day’s participation (I determined the cost from various sources including the Guns-on-Pegs web site which specializes in buying and selling shooting days). That works out to over C$100 per grouse. Because of the huge overhead required to hold a driven hunt (this article in the Journal of Applied Ecology gives a good accounting of this) they are very expensive to run and many estates are barely breaking even or losing money even in good years.

There is a second less expensive form of hunt referred to as the walked-up hunt in which a small group of hunters led by pointers, walk the heather shooting grouse as they are flushed by the dogs. Per brace, a walked-up hunt appears to cost roughly half that of a driven hunt.

Tradition and the Grouse Moorlands

Much of the land here is managed as grouse moor as can be seen by the patchwork of areas on the far hillside where heather growth is regulated by controlled burning.

The Red Grouse does not lend itself to direct management through domestication as do other species such as partridge and pheasant. Instead, maintaining their populations is handled indirectly through the intensive management of the heather moorlands – also referred to as grouse moorlands or simply grouse moors. This lack of direct control means that the hunting season can vary in quality from year to year and location to location depending on weather conditions, predator populations, heather beetle infestations, and disease.

Managing the heather moorlands for grouse is very expensive and requires continuous attention. Gamekeepers will go to great lengths to ensure a large supply of healthy grouse, even walking the moors at night with a flashlight medicating any grouse that they find to help them fight or prevent disease. It should then come as no surprise that the same intensity is applied to managing the grouse’s predators. This usually means eradicating any predator that strays onto the grouse moors. The Red Fox may be hunted at night using lights and high-powered rifles or simply by using of snares. Widely acknowledged to be cruel and banned in most European countries, snares are also prone to catching and killing non-predators and protected species such as the badger (see for instance this 2004 article from Wales online).

Viewed from this side of the Atlantic, this ritualistic hunting supported by intense year-round management could seem odd, even barbaric. Long-standing traditions that are part of the fabric of a country’s cultural heritage can be very difficult to change.  In some cases, however, change does occur. One example is the ending of the fox hunt in Scotland, England and Wales between 2004 and 2005.

Before passing judgement, consider some of the positive aspects of the grouse hunt as put forward by proponents of the hunt.

In Great Britain organizations such as the British Association for Shooting and Conservation, the Game and Wildlife Conservation Trust, and others seem to play a similar role for game hunting as Ducks Unlimited does in North American in support of duck and goose populations. In the case of the grouse, they help promote and maintain the heather moorlands for the benefit of the game birds and for any other bird or animal that may benefit as well.  This includes, for instance, regular burning of patches of heather to keep larger shrubs in check and to encourage younger, tender growth that appeals to the grouse. One of the biggest benefits to the moors is from the reduced number of predators. Several threatened migratory birds breed in the moorlands and in those areas without these predators they thrive with breeding success reportedly 2 to 5 times that on unmanaged moorlands (as most pro-hunt organizations are quick to note).

The Game and Wildlife Conservation Trust has the following goal on their web site:

We promote our work to conservationists, including farmers and landowners and offer an on-site advisory service on all aspects of game and wildlife management, so that Britain’s countryside and its wildlife are enhanced for the public benefit

I suspect that the public benefit they refer to is a select part of the population that benefits from the hunt (the hunters, land-owners and surrounding communities). The benefit to the migratory birds is a convenient side-effect. Meanwhile, those other animals, the predators, that were removed or killed are not mentioned except in so much as they are part of the problem being managed.

The Plight of the Hen Harrier

Hen Harrier

An key part of grouse management involves predator management. According to research used by some of the shooting proponents, the survival of grouse and other species can be several times greater when predators are kept under control. For the unprotected predators such as the red fox, carrion crow, stoat or weasel this is a death sentence should they be caught on or near grouse lands.

A number of raptors also fall on a gamekeeper’s list of predators however most of these are protected species making it illegal to kill them or disturb them while nesting.  With tradition, jobs and large sums of money on the line it is not surprising that the battle lines are drawn between the gamekeepers and other hunting proponents and the ‘raptor lobby’.

[Some interesting insight into the ‘Raptor Lobby’ can be obtained from the Raptor Persecution Scotland blog.]

When discussing Red Grouse management and raptors, one species that is frequently mentioned is the Hen Harrier (Circus cyaneus; the Northern Harrier in North America).  The moorlands are a terrain well suited to their hunting and nesting behaviour yet, despite the laws intended to protect them they are disappearing in many areas of Britain particularly those areas near grouse moorlands.  They and several other raptors including Golden Eagles and Buzzards are frequently shot or poisoned.

This year in England is especially ominous for the Hen Harrier. An August 9th article by the Royal Society for the Protection of Birds (RSPB) entitled: Hen harrier on the brink of ‘extinction’ in England reports that this is the first year since the 1960’s that the Harrier has not successfully nested in England (they mean ‘extirpation’ not extinction of course).  The Hen Harrier, once widespread in Britain, has been harassed by gamekeepers for centuries.  It was previously extirpated around 1900 only to resettle mid-century.  Despite the raptor protection laws, the return to England is proving to be short lived and its future status may be uncertain as long as the economic value of the grouse hunt remains high. Given the economic importance of the grouse hunt, it is hardly surprising that Harriers and other protected raptors are being persecuted.

On the side of the hunt, a 2009 article in the Journal of Applied Ecology, Hen harriers and red grouse: economic aspects of red grouse shooting and the implications for moorland conservation, presents ecological and economic arguments to justify keeping Harrier populations low. It provides good insight into the economics of the grouse hunting industry and the issues facing the Harrier and other grouse predators.

Other opposing research is not as quick to blame the Harrier and other predators but instead lays out a number of other reasons for long term and year-to-year declines in grouse populations including:  conversion of heather moorlands to sheep pastures; deterioration in the heather quality that grouse rely on for survival; increased disease reducing survival rate; increased predation by foxes and crows attracted by increased sheep populations; afforestation; and so on.

In an effort to find real solutions, both sides of the debate have cooperated in some long term research projects to better understand the relationship between grouse populations and raptors such as the Hen Harrier.  A Joint Raptor Study (JRS) was run from 1992 to 1997 to measure the scale of raptor predation on grouse and the effects that would be felt on the hunt.  A new study called The Langholm Moor Demonstration Project started in 2008 and will last up to 10 years with the goal of finding solutions to solve the grouse-raptor issues.

I won’t go into all the details of these studies but one interesting thing that I did learn which shows some of the complexity of the problem, is that the Harrier’s main prey are voles and meadow pipits, not the grouse, and the availability of these influences where the Harriers decide to settle in the spring.  It is only during the months that they are breeding that grouse chicks are at risk of being taken and diversionary feeding (providing carrion to the raptors) has shown the numbers of grouse chicks taken to drop by as much as 86%.

Watching the Magician’s Other Hand

One fact which nobody disputes is that grouse are good for the environment.

That’s a direct quote from an obviously pro-hunt 1996 article published in “The Independent” and accurately sums up the position taken by most pro-hunt organizations.

Having spent some time trying to understand the history, culture and economics surrounding the grouse hunt in Great Britain, I can’t help feeling like I am watching a magician doing an elaborate trick when trying to sort through the shooters’ arguments.  While their main hand attempts to capture my attention with statements of environmental and economic goodness, there other hand is quietly doing whatever it takes to make sure the grouse are ready on August 12.

The arguments for and against the grouse hunt and predator management are many and, sitting on the other side of the Atlantic, I don’t feel qualified to mark the scorecard.  Instead, I will direct my final thoughts in a different direction going back to what drew me to write this in the first place, the name given to the opening of the Red Grouse hunting season.

Introspection

They call it the Glorious Twelfth.

Being a long-time fan of Star Trek the word glorious makes me think of the Klingons, warriors with tradition and a code of honour, their battles gloriously fought against enemies that are, they hope, worthy adversaries.  The grouse hunt certainly has its tradition, however  I wonder if a Klingon would feel glorious standing in a box waiting for someone else find and deliver their quarry to them, killing wave after wave of them with no chance of the quarry fighting back, the biggest risk coming from a neighbouring hunter?  I wonder if they would feel any honour participating in a sport for which so many foxes, crows, stoats, weasels, other predators and even innocent creatures that had been killed, sometimes cruelly, in order to ensure the maximum number of grouse for the final slaughter?

The Glorious Twelfth doesn’t really do the day justice.  Perhaps, as suggested by the birder and blogger Alan Tilmouth from Northumberland, a better name would be Hen Harrier Day.
