Thank you to Elsa, Mongo, Peter and Mike for your kind comments.
Some cunning strategy there too Mongo. If the truth be known, these images are very opportunistic for me.
There are periods of several hours when the birds don't come and I generally have slots of maybe 20 minutes before & after work when the light is actually good enough. Also the Jays are very easily spooked if they detect any movement.
But sometimes it all falls into place - here is one I took last year when the pair were teaching their young how to feed.
We'd never had them visit us before and were so pleased. Now grateful they've come back this year.
I'm guessing it's the Dad here has got his head feather ruffled - the relationships between parents and children seem to be just as challenging for all living creatures !!
