To describe my lifelong fascination with flight and with creatures that fly I like to echo the words of John James Audubon who in 1839 wrote of himself as "...one who never can cease to admire and to study with zeal and the most heartfelt reverence, the wonderful productions of an Almighty Creator."

Northern Carrion Beetle (Silpha lapponica)
This beetle, and two others identical to it, were in the nestbox of the Violet-green Swallows today. I watched them rummaging around in the grass and feathers of the growing nest, and captured them when they crawled out. I believe they are Northern Carrion Beetles (Silpha lapponica) which may explain why the female swallow carried them into the nest: according to one source, they feed on fly maggots.

Winter Wren on territory
This Winter Wren was staking his claim to a piece of McMinnville's Rotary Park this morning by singing from high and visible lookout posts. I can't think of any species that has a longer song in proportion to body size than this one. With a total body length of 4 in. including tail and bill, his lungs cannot be very large. Does he sing on both exhale and inhale?

Hairy Woodpecker perched
Here's another shot of the Hairy Woodpecker near the nest I found last week, but she is not in a typical woodpecker posture. At the time of this photo she was very agitated and making a lot of scolding/warning sounds because of the Cooper's Hawk nearby. Maybe at such times she feels safer in a position where she can see in all directions, rather than on the side of a tree which blocks much of her field of view.

Even though it is one of the most "famous" birds of North America, the Spotted Owl is actually seen by relatively few people. This week I had a chance to see one only a few hours after hearing the calls of a Barred Owl. Some knowledgable people are saying the the Barred may be an even bigger threat to the Spotted than logging is here in the Pacific Northwest as it continues to invade and take over the Spotted's habitat.

Hairy Woodpecker at nest
This female Hairy Woodpecker was feeding some noisy youngsters in this nest cavity last Saturday, May 13. There is also a Cooper's Hawk pair nesting in the same grove of trees along the Willamette River, which does not bode well for the lifespan of the young woodpeckers when they leave the nest in a week or two.

Beetles in the Swallow nestbox
Yesterday was a very interesting day inside the nestbox of the Violet-green Swallows. The female brought in at least seven live beetles of at least four different kinds. Five are visible in this photo. She obviously didn't want to kill them or eat them. She occasionally would pick one up and drop it again. Then she would just stand still for several minutes, seemingly just to watch them crawl around in her house. Her purpose in doing this is still a mystery as far as I know.
Vaux's Swifts entering chimney
Vaux's Swifts are again putting on a show every evening in our town (and probably in many towns in Oregon) as they go to roost in chimneys for the night. This flock of about 1,000 on my street will probably disappear within a few days as they scatter for the nesting season. I wonder how they decide which pair gets to stay in this one.

At this time of the year, here in Oregon's Willamette Valley, it is quite unlikely that you could be near a patch of woods and not hear the song of the Black-headed Grosbeak. It does require some practice at first to distinguish it from the Robin's song, but a careful listener will soon recognize the fact that it is even more melodious. This one was singing this evening in McMinnville's Rotary Park.

Violet-green Swallow sleeping
On several occasions in the past two weeks I happened to be watching when the female Violet-green Swallow came inside just before dark, appearing a bit disheveled, and almost instantly went to sleep, eyes covered by white eyelids. This evening it happened at 8 o'clock while the sun was still shining directly into the box. She didn't let it keep her awake, but after about five minutes, she roused enough to preen for a few minutes, and then went back to sleep. Earlier in the day she had brought in a few new grass stems.

In contrast to several decades ago, the Osprey now seems to be thriving in Oregon's Willamette Valley. This morning this one, which appears to be a female because of the "necklace" of brown streaks, was perched beside her nest on a utility pole. But I'm a bit puzzled by the situation I observed because this bird's mate (which I could not see very well) seemed to be keeping eggs warm in the nest, and I've never observed a male being allowed by the female to stay on the eggs when she is close by. I'll have to watch this pair closely to see if perhaps this is one of the occasional males that shows some of the brown "necklace" plumage.

While many other species in our area are already incubating eggs, or even feeding young, the Violet-green Swallows are apparently waiting, as usual, for warmer weather. Today was warmer than recent days, and the female was inside the nestbox at least three times. The timing and sequence of her progress so far this year is remarkably similar to last year. How do they know when the time is right to begin building?
