More Migrants & Young in the Nest

Today there were a couple of stations where the birds sang incessantly. This occurred early in the morning before winds picked up. Heavy overcast skies and bouts of sprinkles kept me from traversing my bike route until later in the morning.
I took advantage of this time to stop in the bird blinds where I saw a Yellow Warbler and Swamp Sparrow. After surveys were completed I visited the blind again and picked up a Gray Catbird. Blind hosts also reported Orchard and Baltimore Orioles today plus a first of year Yellow-billed Cuckoo.
The first Acadian Flycatcher arrived at one of my stations. The Black-chinned Hummingbird nest has two half grown nestlings being tended to by the female. These nestlings' bills are about 3/4" long. There were also multiple Swainson's Thrushes singing along the river this morning. This is the first time they have been so vocal during spring migration. This year there is only one Canyon Wren on territory at my stations. Numbers have gone down of this species over the past two years. Listen to its song by clicking on the name above which directs you to Cornell Lab of Ornithology's web page. Then select Sound. It is a musical descending cascade of liquid notes.
