We further analyzed whether sperm collection success rate depended on the behaviour of the focal male/pair just before catching the bird.We found that sperm collection success indeed depended on the behaviour of the birds(Fisher’s exact test,n=85,p=0.022),with males trapped when they were about to mount their females being more likely to ejaculate semen containing live spermatozoa(Table 1).Other behaviours(female begging for food,after copulation or bird doing nothing)were unpredictive of our success to collect live sperm.
