Agelaius phoeniceus (red-winged blackbird)
Another group songfest - this time from a "Lek" of 25 or so Red-wings in the morning. I'm not sure this is a true Lek, but the ingredients are all there - lots of males (2/3 of those in attendance are male) singing with lots of females listening, and since it's in the Spring (2/16/99) and in the morning, it seems like Lek behavior. Note the silence midway through the sample - sudden and almost orchestrated - something distracted them for a moment.
