Pacific Swallow – social behaviour while nesting

YC Wee
on 28th April 2022

I saw a pair of nesting Pacific Swallows (Hirundo tahitica javanica) in an urban/public setting. One bird was incubating. The other was nearby and would intermittently visit the nesting site and appeared to feed the incubating bird. I saw this on 4 different occasions in an 8 minute observation. The bird would fly around to collect prey and after 5-7 were collected, it would come over to the nest and appeared to give them to the other bird (above and below). I am not aware of such behaviour previously and do not know if this is common behaviour. The bird on the nest is an adult to my observation and was not begging for food as juvenile usually do. I did not watch for too long as I did not want to bring attention to their nest.
