Pacific-slope Nestlings 10 Days Old

July 21: As of yesterday the Pacific-slope Flycatcher nestlings are 10 days old. Their eyes are opening and feathers are starting to show. They also appear much more restless than in previous days and I’m a little worried that one might fall out of the nest. It’s more than 6 feet down to the concrete steps so a fall would, I imagine, be fatal.

The adult birds spend most of their time foraging and only at the nest for a few seconds every few minutes. So, I thought that I’d try to get a better between-visits picture of the nestlings with my Panasonic FZ-200 camera whose 24x optical zoom lets me fill the image whereas the Logitech 920 webcam, used for my videos, has no optical zoom so cropping is the only way to “zoom in” and that results in a lower resolution image. Here is the best picture that I was able to take:

P1180474

I had just focussed on the nestlings, who were alone in the nest, when the adult male flycatcher appeared in the foreground. Because of the low-light I was using a large aperture with poor depth of focus which put the adult bird slightly out of focus. It’s a nice subtle effect.

The camera picture also highlights something else not so nice. If you look closely at the vinyl siding behind the nest you can see a number of small black specks. Reviewing the webcam videos shows that these specks are actually moving around. They are concentrated around the nest suggesting that they are some form of parasite associated with nest and birds. I reviewed previous days’ videos but July 21 was the first day that the specks were visible. My suspicion is that they are bird mites which Doctor Google tells me would not be a good thing. More research needed.

Pacific-slope Flycatcher Nest

June 26: This was the day that we noticed the nest being built on top of the light in our front entry way. Our first thought was a swallow because we have a lot of them flying around our neighbourhood though most would have nested weeks earlier.

June 28: We noticed a bird sitting on the nest so I got out my camera and we discovered a Pacific-slope Flycatcher (whose 4-letter species ID is PSFL) sitting on the nest. Here is the picture that I took:

PSFC Nest P1180287

Consulting with Birds of North America Online (BNA-online) I discovered that first broods occur in April or May but some pairs will attempt a second nest around June or July. This was clearly round 2 for these birds.

June 30: I got up on a step-stool, held my iPhone 4s above the nest and took a picture:

The PSFL was sitting on 3 eggs. Consulting BNA-online again I found out that the most common number of eggs is 4 followed by 3 so we might have a full nest or there may be more to come.

July 2: Only 2 days after the first picture, I took a second and discovered that there were still 3 eggs.

July 5: Another 3 days and there were still only 3 eggs to the bird sitting on the nest was probably incubating the eggs. BNA-online indicated typical incubation periods of 13 to 16 days so, assuming that my first ‘egg picture’ indicated the start of incubation then we should expect the eggs to hatch between July 12 and 15.

July 11: A picture from my iPhone shows that the eggs have hatched:

The three ‘grubs’ in the nest look pretty helpless so they must have hatched quite recently.  I decided to call July 11 hatch-day 0.

Here is my first video of the adults coming and going, bringing food to the nestlings.

There will be many more videos and pictures to come as the nestlings grow up and fledge. I just hope that they all make it to fly away risking the odds of survival which are not in their favour — I’ve heard that only about one in ten birds survive a year after hatching.

Gulls Eating Sea Stars

Back in August of this year, the 14th to be exact, I was walking along the waterfront in Sidney, BC when I caught a gull red-handed (or red-billed) trying to swallow a sea star. Here’s the sequence of 4 pictures that I took over a half-minute or so:

Gull Eating Sea Star 1 of 4 - P1170385 Gull Eating Sea Star 2 of 4 - P1170386

Gull Eating Sea Star 3 of 4 - P1170387 Gull Eating Sea Star 4 of 4 - P1170388

The gull does not seem to be having a lot of success.

Then, I was looking through some older images yesterday and found another sequence of 4 images taken in March 2016 at Neck Point Park in Nanaimo:

Gull Swallowing Sea Star 1 of 4

Gull Swallowing Sea Star 2 of 4 Gull Swallowing Sea Star 3 of 4

Gull Swallowing Sea Star 4 of 4

The first image shows the gull with the sea star in its mouth. The following three images show the gull swallowing the sea star. It had to extend its neck which, as you can see by the white spot on the rocks appearing in the third image, triggered a ‘movement’.

Unexpected Finds at Buttertubs Marsh

I was birding Buttertub Marsh with a friend last Thursday (November 17, 2016). We were scanning the almost empty pond for waterfowl when Leonel noticed 4 Great Fronted Geese hanging out with some Canada Geese at the far side of the pond. It was the first time that I had seen them there.

Here’s a picture captured with my Panasonic FZ-200 at maximum zoom. It’s cropped as well. You can also see a bird in front just to the right of centre with a neck-band as well. I’ll say more on this guy later.

GWFG at Buttertub Marsh

Four Greater White-fronted geese mixed with some Canada Geese at Buttertub Marsh on November 17, 2016.

About and hour and a half later we were just about done and noticed the Canada Geese swimming more in the middle of the pond without the GWFG. It was Leonel’s good eyes and my FZ-200 to the rescue a second time. The 4 geese were across the pond on the edge of the pond resting, their coloration blending in well with the background reeds.

VIU Canada Goose Project

I said that I’d come back to that Canada Goose with a neck band in the first picture.

A group from VIU, headed by student Stew Pearce, banded 200 Canada Geese earlier this year and has been following the locations where they have been seen since using information sent in by birders or anyone else interested in helping out. The goal is to learn how the birds move about during the year. You can find out more by going to the VIU Canada Goose Project web-site.

Stew told me recently that geese from the project have been seen and reported from as far away as Portland, Oregon. So, if you happen to see a Canada Goose with a neck band let Stew know using the instructions at the above link.

So, did I figure out what the ID of our find was? Yup! We saw the bird swimming behind some reeds an hour or so after our first encounter and I took a some pictures as the goose swam in and out of view. One of the four was clear enough to ID the goose:

Our goose’s ID was “096P”. I checked the web-site and discovered that the most recent sighting was November 6 at Buttertubs Marsh. I’m guessing that this guy is not going South this winter.

 

Watching Coot-Looting Wigeons at Buttertubs Marsh

I sometimes wonder why I don’t get bored going to the same birding locations month after month, year after year.  A big part of it is that, on any given day, there is a chance that they will see something different or rare or perhaps even totally new.

This past Sunday, while on an organized outing with a bunch of local birders to Buttertubs Marsh Bird Sanctuary in Nanaimo, I got my “something-new” fix.  In this case is wasn’t a new species of bird — instead it was an inter-species interaction that I had never noticed before – that of an American Wigeon stealing food from an American Coot.

Scene 1: Following the Coot

Coot (Fulica americana) & American Wigeon (Anas americana)

The first of the two species, the American Wigeon (Anas americana), is a duck that is part of the genus Anas sometimes referred to as dabbling ducks.  These duck may feed on land or on the water where they can tip themselves upside down and gather underwater plants up to several inches below the surface.

The second of the two species, the American Coot (Fulica americana), is in the family Rallidae of rails and looks a little like a small black chicken.  These birds may feed on land, by dabbling in shallow water or by diving for plants.

I captured a short video of the food stealing behaviour (kleptoparasitism) with my Panasonic DMC FZ-200 camera.  I may have had too much fun and gotten a little carried away with the presentation.  You be the judge:

At one point there were at least 3 or 4 Wigeon-Coot pairs doing similar food-stealing dances.

On another occasion I watched as a Wigeon tried to manage two Coots at the same time and seemed to spend a lot of time in the middle trying to decide which way to go.  Not a good strategy for a low-intelligence bird it would seem.

Some further comments and other notes resulting from forays into online ‘research’:

  • A 1979 article suggested that the Wigeon is the only duck known to be a regular kleptoparasite (ref [3]).
  • A 1984 article documents Gadwalls stealing food from American Coots (ref [4]).
  • Other ‘dabbling ducks’ in the genus Anas include the Mallard, Wigeons, Teals, Shovelers, Pintails, the Black Duck, the Gadwall and a few others.
  • Wigeons apparently will try to steal food from other diving water birds, not just from coots.
  • Coots, in turn, have been known to steal food from other water birds.
  • Coots will also dive to escape predators (the Coot is one of the easiest birds for the Bald Eagle to catch).

Post Election Birding in Nanaimo

I made my first post-election birding trip yesterday.  A friend, who I’ll refer to by his initials LR, and I set our Nanaimo itinerary to take us on a loop including Neck Point, Pipers Lagoon, the Nanaimo River Estuary and Buttertub Marsh.

We should have known better as we only made it to Neck Point and Pipers Lagoon spending more than two hours at those two sites.  We did add the Linley Valley Drive Wetlands which is walking distance from our house.

As usual, I had both camera and binoculars at hand.  Birding was enjoyable and I did get a couple of nice pictures that I’ll share.

Neck Point

We arrived at Neck Point and had barely got out of the car when the buzzing (for an example play this recording of a Bewick’s Wren on Xeno-Canto) of a Bewick’s Wren was heard.  There was actually a pair flitting around near the parking lot and they were surprisingly unafraid bopping around in plain site.  Here is one checking me out:

Bewick's Wren at Neck Point, Nanaimo, 2015-11-05

Bewick’s Wren at Neck Point, Nanaimo, 2015-11-05

Note that I rely heavily on the auto-focus feature of my camera (Panasonic FZ-200).  When taking of pictures of fast moving birds, especially when they are in bushes the auto-focus does not always behave.  Here is an example:

Camera misfocus on Bewick's Wren.

Camera misfocus on Bewick’s Wren.

Apparently the camera liked the road-side pebbles better.

We saw a total of 14 species at Neck Point (eBird checklist)

Pipers Lagoon

Pipers lagoon was more productive producing a total of 23 species (eBird checklist).  The picture bird, a male Hairy Woodpecker,  was again located first by sound (here’s a recording of a Hairy Woodpecker on Xeno-Canto).  Here’s a picture that shows the long bill (compare with the shorter bill of its smaller look-alike cousin the Downy Woodpecker):

The final picture, while not of the highest quality because it was taken at full zoom, proved to be useful for the identification of a pair of gulls sitting on a small rock offshore.  The yellowish legs and plumage suggested a California or a Mew gull.  Studying the picture later suggested that it was a Mew Gull.  Check it out for yourself:

Linley Valley Dr Wetlands

A two minute walk from my house is a small wetlands  surrounded by housing developments in various stages of completion.  We spent about a half hour walking the path that runs along one side of the pond and saw some interesting birds (5 new species for the day) including a Hooded Merganser pair, Ring-necked Ducks, a Fox Sparrow, Chestnut-sided Chickadees (surprisingly not seen at the other two locations) and a Pied-billed Grebe.  The site total was 12 species (eBird checklist)
