观察细节
I watched and took photos of 8 adults feeding at least 2 young in mud nests on the southern side of a bridge over the Redbank Creek and it also appeared that more or these 8 adults were also going up under the bridge where there were 4-5 'panels" so not sure how many in all;;;am attaching a few photos but I numbered my photos for myself (to 15) so I could see adults going to each hole to feed;;;they also were flying (catching bugs) all over the water and the air above the land...I could see the brownish cap/head with buffy orangish rump on some;;;hard to see every detail when they fly so fast and there are more than a few;;;plus there were a few other swallow species, I believe tail length is also a factor between the species;;;;
