Thrush

After several days of overcast and rain, I took advantage of unforecast afternoon clearing and went for a walk to Totem Park. Later I stopped by Swan Lake to check things out on our way to have dinner with friends.

Weather: Overcast, with clearing skies in the afternoon. A light breeze was out of the southwest.

Birds: I have been hearing a Steller’s Jay in the neighborhood lately, usually in the morning.

Down at the park there were few shorebirds, I think I heard some Black Turnstones and the hummingbirds seemed to have moved on.

There were probably a couple of hundred gulls on the south/southeast beach.

I saw several Winter Wrens. There plumage was a little ragged which makes me wonder if they are going through a molt.

I saw one Varied Thrush and at least 2 different Catharus thrushes in the berry bushes on the river side of the fort site. It appeared they were going after the ripe huckleberries.

I saw one warbler in the fireweed, I think it was an Orange-crowned Warbler, but I did not get a very good look.

I realized it has been awhile since I last saw an American Robin while I was in the park. I then saw one fly by just as I came out of the woods. I think the local breeders have moved south.

This evening at the lake, in addition to the many mallards, there were two Hooded Mergansers and one Green-wing Teal. At least one of the mergansers appeared to be a juvenile.

Other Notes: The fireweed still has not started seeding yet. They also looks like they have far more flower buds than can possibly have time to bloom this summer.

There was a squirrel eating huckleberries at the fort site.

There was a dragonfly near the fireweed area. It seemed like it prefered to rest on vegetation and would only fly for short periods of time after it had been spooked from its resting place. It was a darner of some sort, but I am not sure what species.

Harbor Seals

Harbor Seal Haulout

On the second tour I had today, we pulled up near the rocks a little South of Povorotni Point in the opening of Redoubt Bay to observe the Harbor Seals. Perhaps it was the relatively bright weather, but it seemed like there was an unusually rich assortment of colors and patterns of seal fur. This fit in nicely with one of the things I like to tell the passengers about seals. It is relatively uncommon for there to be significant difference in appearance between individuals in a species. It is somtimes possible to identify individuals based on subtle differences, and there are often signficant juvenile/adult or male/female differences, but for the most part the overall coloring of an animal within a specific population group will be very similar. This is not the case with harbor seals. Until this job with Allen Marine, I had not had much opportunity to see seals hauled out and had never really thought about this fact. I am pretty sure I learned about it on Encounters a locally produced program that
emphasizes experiences in the Alaskan wilderness.

One of the other things I often tell folks is how the seals will float in the water as the tide is going out so they do not need to climb up on the rock. Unlike Steller’s sea lions, the harbor seals seem to be weak climbers. It seemed that no sooner had I said this when I noticed a seal climbing out of the water up on to the rocks. This was followed by a second and third. I felt a little silly, but tried to recover by noting how their climbing was fairly labored and weak, and I had not seen them doing this before. I did not think much about it until later.

After we dropped our passengers off at their cruise ship, the captain told me that there was a pod of orcas teaching their young to hunt. He said as we were rounding Povortni Point he heard on the radio from another Allen Marine vessel that the orcas were at Caution Island with a harbor seal. We were already running just a little bit late, so we couldn’t afford to go back (as it was, the ship left promptly after we dropped off our passengers).

The news we heard from the boats that were able to watch was the adults were using a harbor seal to help their young practice hunting techniques. The adults would keep the seal from getting away and demonstrate techniques of attacking and stunning an animal in preparation for eating it. These include ramming, slapping with tails, and jumping out of the water to land on top of the prey. Apparently a later boat saw them actually consuming the seal. I imagine that the final minutes (hour?) of the seals life was terrifying, the stuff of seal nightmares. I can’t help but think the seals that were uncharacteristically climbing up on the rocks (which we observed probably about an hour before the orcas were spotted) knew the orcas were in the area and wanted to get out of the water if at all possible.

The last I heard, the orcas had turned their attention to ‘playing’ with a common murre. Based on what I have heard previously, it is unlikely that they will consume the bird, but they do seem to use them on occasion to practice hunting techniques.

It was a little disappointing to find out we just missed this opportunity to see some orca activity. It is my understanding that these animals move through Sitka Sound on a fairly regular basis, but they move quickly and do not seem to stay in one area for long, so seeing them seems involve getting a little lucky sometimes. People who have worked these tours for a number of years told me they usually only see orcas a handful of times a year. What made today even more interesting to me was that just yesterday I read about an orca/harbor seal encounter witnessed earlier this month north of Sitka (scroll down a little to see photos and link to video; scroll down into the comments to see a more complete story, the comment begins The story in two parts).

Whispering to Raven

Whispering to Raven

A mixed flock of small song birds was foraging at the edge of the forest in Totem Park today. When they reached a clearing where a totem pole is located, some of them perched briefly on the pole. It looked to me like this Townsend’s Warbler was whispering to Raven.

Pacific Slope Flycatcher

Took a couple of trips down to Totem Park today to take advantage of brighter skies.

Weather: A little bit of light rain and mist today, but there were also some significant spots of blue sky and sun. Winds were light out of the west this afternoon.

Birds: I took advantage of the brighter drier conditions to get some photos of the humming birds that were still feeding in the fireweed.

There was a very loose mixed flock of birds that I noticed moving through the trees along the beach edge of the forest. There were Wilson’s Warblers, Townsend’s Warblers, at least one flycatcher, at least one Ruby-crowned Kinglet, Chestnut-backed Chickadees, and Golden-crowned Kinglets.

There were several warblers that spent some time in the fireweed while I was watching the hummingbirds. I got a good look at Orange-crowned Warblers, a Wilson’s Warbler or two, and possibly a Yellow Warbler.

The shorebirds have practically disappeared. I counted maybe 5 Least Sandpipers, 1 Greater Yellowlegs, and 1 Spotted Sandpiper. I did not look over by the river, so there may have been another shorebird or two over there. However, the tide was up, so I don’t think there was too much over that way.

Other Notes: A lot of mushrooms are coming up in the park.

An interesting looking moth flew up while I was sitting on the beach holding out some hope for shorebirds. I got some photos of it (I’ll probably post some later). When I showed Rowan the pictures and asked her she knew what it was, she thought it looked like bird poop. If that’s what is trying to imitate, it could do better, but I thought it was interesting that she came up with bird poop.
