DuVal, E.H. 2005 Journal Isla Boca Brava, Chiriqui, Panama 28 April 2005 I was again netting for unbanded females with chicks today. The next A-4 mom was caught as she mobbed me after I banded + bled her chicks. She flew away strongly and suffered no feather loss, so I hope that she won't abandon the chicks. The second nest of the day was 5-10, which has chicks just slightly younger (8 days?) than the A4 nest. That female, too, mobbed me as I bled the chicks, but she nicely avoided the net which was somewhat lower than her mobbing path. After about 10 minutes I retreated to see if she would fly lower with a less direct threat. When I checked the nets, I found only the larger chick still in the nest. The smaller one was on his back on the ground with a small amount of blood under one wing. It seems that the female threw him out of the nest, possibly because of the presence of blood. Both chicks had one plastic legband, and were placed in the nest so that the sibling shielded the banded leg from view. The chick that was on the ground had a yellow band, while the chick in the nest had a red band. I cleaned the residual blood off of the yellow-banded
