Communication

Even young swallows how a trick or two I've seemingly missed in life. Amazing how these four siblings could sense the approach of a parent before I could see him/her enter the shed. I did learn from them however that every time they opened their beaks it was time to concentrate.... Wish they'd tell me how to shoot at a lower iso for clarity... As it was quite dark iso is 16,000 as I needed 1/2500 to get the parents in flight...just saying
