Caption
This unusual "piping" by a male Red-winged Blackbird was directed at an interloping male. The calls were actually about 5 seconds apart, but I took out some silence in the interest of bandwidth here. I'd not heard this call used to warn another male before, but the intruder got the point and soon left the area.
