The Flycatcher
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."

Red-breasted Nuthatch feeding activity
To watch a short video of the Red-breasted Nuthatches now feeding their young at the opening of the nest cavity, go here:
Notice that the nestling rejects one item of food, and then produces a fecal sac for the parent to dispose of.

Osprey with fish pursued by crows
Yesterday I happened to be standing on the shore of the Columbia River in the town of Hood River, Oregon, when an Osprey glided by into a strong west wind about 100 ft. above the surface of the water. Suddenly it plunged straight down into the water and came up with a fish. Almost instantly there were several crows swooping and diving at the Osprey, apparently trying to cause it to drop the fish, but to no avail. The Osprey had a firm grip with both feet, and soon the crows gave up the chase.

Red-breasted Nuthatch use of pitch
I had read about the Red-breasted Nuthatch's practice of placing sticky substances around the opening of the nest cavity, but had not had opportunity to observe it until this one chose to nest in my yard. I touched the stuff to see how sticky it is, and also to smell it. It feels and smells exactly like the pitch from a Douglas Fir tree, with which I am very familiar.

Red-breasted Nuthatch nest
A pair of Red-breasted Nuthatches are busy feeding nestlings in this cavity in a hawthorne tree in my yard. Some of the food items being brought to the nest appear to be small spiders. A short video recording of some of the activity is here:

Spring birds
Spring migration is interesting because of both who is arriving and who is leaving. I still have a small group of Golden-crowned Sparrows in my yard here in Oregon, and they are supposed to be on their breeding territories somewhere in British Columbia and Alaska in just a few weeks. How do they know their patch of boreal forest is still snow-covered? But also today a House Wren was checking out a nestbox here. I wonder if he wintered in California, or possibly in Costa Rica, and what adventures he had getting here.
