Great-crested Flycatchers arrived on my patch more recently, but one has been hanging around the same grove for a few days. I am not sure if it is the same individual. A few others were present yesterday, in different parts of the park and calling from across the river.
One bird that is unlikely to nest in the park is this Rose-breasted Grosbeak. I see them on my patch rarely, and only during migration. There are other places locally where they would be likely to find better habitat, though. In the case of this bird, it was the song rather than the flashy colors that caught my attention. That usually seems to be the case – despite its white undersides and flashy red collar, these birds blend in quite well with the canopy. Another song that caught my attention was that of a Chestnut-sided Warbler. I did not manage to track it down to admire its spring plumage, but it was a new bird for me in Middlesex County.
