Close countersinging of two birds in the Edmund Forest of St. Lucia
BACK
In St Lucia I observed two Rufous-throated Solitaires sitting about a foot apart and singing. At first I thought only one was singing, but then I looked closely and noted that both were singing, the one perched higher, and mostly unmoving, singing first, the other flying around from time to time, always perched lower than the other and nearly always singing second. The first time I recorded the second bird singing first, a fight ensued almost immediately. Here are the pairs of songs sung over a period of two hours. These pairs would be repeated many times before changing. The inter-song delay is as shown on the spectrogram, except for 3 and 4 in which I reduced it from around 6 seconds to around 3 for presentation. Click on the spectrograms to hear the songs. Note the near equivalence of the songs in pair 3.
