At the end of the island and in the marsh, there were swarms of swallows. Almost all of these were northern rough-winged swallows, a species I had not seen since last July. They darted back and forth across the water in the typical swallow fashion, flying swiftly, then suddenly reversing course. At times, they seemed to stop in midair before changing direction. Among them were a few slightly smaller swallows with more deeply notched tails, white throats, and brown neck bands; these were bank swallows.
A few killdeer were in the marsh. While these are not entirely unexpected at Roosevelt Island, I usually do not see shorebirds (killdeer or otherwise) at this location. Wood ducks, both on the riverbank and in the marsh, were another pleasing sighting. Several hermit thrushes flocked around the Roosevelt Memorial near the entrance.

At right: blurry footage of a large, crested woodpecker.
Along my walk, I found a red-shouldered hawk nest. Or, perhaps it is better to say that the nesting red-shouldered hawk found me. As I passed by the nest, the proud parent starting calling vociferously. I stood off a bit where I was less conspicuous and watched through my binoculars as it shook its feathers and shifted position on the eggs. I will have to check back there to see if they hatch.
The pair that is nesting at Roosevelt Island is one of several breeding pairs in the District. Other pairs of breeding red-shouldered hawks have territories in Rock Creek Park, Kenilworth, and the National Arboretum. There may be another pair in the Catholic University area, and possibly another along the canal. While the species may be declining overall, it seems to be thriving in D.C.
