This is a House Swift. Pacific Swift would be larger with longer wings and a deeply forked tail.
I hope the bird was OK - they usually fly all the time, and can have difficulty getting back in the air when grounded. Author: russcath Time: 3/02/2011 15:04
Thank you! It was picked up by SPCA. The final condition unknown.
PS I had the correct family! My friend thought it was from the falcon family.
