Lots of activity down at the Charles River Peninsula early in the morning (including someone camping in a tent by the riverbank and loose, misbehaving, lab puppies).
On the way of the house, I caught one of my favorite spring sounds--counter-singing chickadees. My understanding is that "high quality" black-cap songs start at the proper frequency (around a B on the piano) and then move down around an A for the last two notes (this is the song lady chickadees like best). But during this counter-singing, there seems to be a lot of play in the starting note and I can't ever tell whether it is intentional or just a young fellow who can't quite get the pitch right. Note: robins can be heard singing in the background but they seem quite tentative still.
The fox sparrow is still singing down at the CRP. I have two excerpts. One song sounds like "hey kitty kitty." And near the end you can hear hawkish sounds--I don't know if this was a bluejay or the love coos of the red-tails (who were making out).
The second fox sparrow excerpt, punctuated at the end by a flicker (who was singing from atop a bluebird house), features a different song (competing with song sparrow and red-winged blackbird songs).
Finally, the early spring chorus wouldn't be complete without a sample of blackbird cacophony. Huge flocks are still passing through (I saw one Cooper's Hawk in direct pursuit).
