Feeding the chicks at BoxA Western purple martin, Squamish River estuary

Box-A Observations For Sunday morning . August 4, 2024 7:55am to 8:45am
Bright sunny morning, hot, no wind.
Between the two structures there was only one Purple Martin hanging out nothing else. I set up my camera on Box-A and kept it running for 50 minutes. During my time there it was clear that there is activity going on at almost every box. Lots of coming and going you just have to camp out for a while to see it.
