Yellow Warbler Singing

Recently I have been asking people if they have seen any Yellow Warblers this spring. While not an especially common species along the road system in Sitka (mostly due to lack of preferred habitat, I suspect), in many years they are show up around the first week of May. However, this year there I had heard of no reports, so I was curious if there were any around.

Early this morning I went for a walk around the neighborhood and heard a bird singing. I thought it might be a Yellow Warbler, though I am not so familiar with their song that I easily remember it, especially the first time I hear it each spring. The bird was moving around in a dense salmonberry thicket. From time to time I could see movement through the branches and leaves, but I was not able to get a good look. Eventually I was able to get the photo above in the brief moment it was partially visible through the leaves. Until I was able to look at the picture more closely, I wasn’t confident that it was a Yellow Wabler, but the look of its face and the streaks on its breast clinched it for me.

Mystery Flycatcher photo composite

My son pointed this bird out to me this morning as we were on our way to Totem Park. It was perched at the very top of a mid-sized Sitka Spruce and I saw it do a flycatching loop once or twice before it seemed to vacate its spot when a Merlin flew by, after which we continued on to the park.

It was too far (high) to get a very good look, even with binoculars, but based on what I had seen, I was confident that it was a flycatcer, and thought it might be a Western Wood-Pewee based on behavior and an impression of size/shape (that is, it seemed a bit to small/squat for an Olive-sided Flycatcher based on my very limited experience).

When we got back a while later, we saw the bird had moved to a snag not too far from where we had first observed it. Though the light was better, the new preferred perch was even higher and further back than the first had been. I watched it for a while several different times during the day, and it was still actively flycatching from the snag until around sunset at least. The first time I saw it there was shortly before noon, so it had been there for at least 8 hours, and probably a couple more.

Though the bird was too far away for any chance of a quality photo, I took many in hopes that they would show enough details to allow for a better chance at a positive identification. I have included the best of these in the composite shown above. My best guess is still Western Wood-Pewee. The behavior certainly fits. However, some of its plumage characteristics raise questions in my mind. In particular, it seems to be rather pale breasted, the wing bars seem to be a more pronounced than I might expect, and there’s a pale area between the eye and the bill. Still, I’m not sure what else it could be. I wouldn’t be surrprised if these questions can be explained with lighting and/or variability in the species, so I’m hoping others with more flycatcher experience might help me out.

Last summer I noticed these white growths while doing some plant surveying work along Blue Lake Creek. At first glance I thought maybe they were rootlets coming from the trunk of the tree (either Red Alder or Sitka Willow, I can’t remember which). Closer examination revealed that they were actually growing directly from the moss. The only thing I have noticed growing out of a moss like that is sporophytes, but there are also sporophyts present and they seem different enough to make me think that the white growths are not a stage in the development of the sporophytes (though perhaps I’m wrong about this?).

I believe the moss is a species of Hypnum though I am not sure which one. So far, this is the only time I have noticed anything like this, so I am tempted to say it must not be very common. However, experience has taught me that I overlook many things, so I don’t really know how common it might be. In any case, I would appreciate any suggestions as to what might be going on with these growths.

A note on the photo: the image seen here was created from 3 initial images, each focused at a slightly different point. They were then stacked to give a greater depth-of-field using CombineZM.
It didn’t work perfectly, so there is a little bit of a funny look to some parts of the photo.

Another stormy night with lots of wind and rain through much of the night, especially the very early morning hours.

Mystery Call: This is almost certainly a gull. I am not sure which species, though. My best guess would be a Mew Gull or maybe a Thayer’s Gull. I do not know what it was doing flying over at 00:57 during a relatively calm period before the wind and rain kicked up again. Download Mystery Call
