i sat and watched this pair of Bluebirds feeding their young, the nest was inside a slide in the park, funny thing was i could hear people saying "whats he shooting at", " must be birds high in the sky because he has his lense extended", i turned around to see them looking skywards, lol, didnt have the heart to tell them.
they were constant with the feeds, the mother was in first go everytime, dad had lots of refusals and sometimes making it on his 3rd go.
