Grey-rumped Treeswifts incubate single egg in a tiny nest

posted in: bird, Grey-rumped Treeswift | 0

Shahrul Kamal learnt from other photographers that a pair of Grey-rumped Treeswift (Hemiprocne longipennis, Family: Hemiprocnidae) was incubating an egg in a tiny nest.  He spent 2 hours at the location in Queenstown, Singapore.

The male (red ear coverts)  and female parent took turns to care for the lone egg, defending it from predators and keeping it warm. Estimated time of changeover shift – 50 mins to an hour. He waited out 2 shifts.
These photos capture some of the actions that took place during the switch and the incubation process. At one point it was drizzling.
The nest is very teeny weeny and attached to a branch.
Local Status – Uncommon resident.
This treeswift belongs to a different Family from the true swifts (Apodidae).
