Am impressed with your Hawfinches Jos!...How frequent are they in your abode? Presume you have baited them with Sunflower seeds?
From March, pretty regular, usually breeding hereabouts.
I don't bait in particular for them, but they are attracted by the usual garden feeders - they will also use the peanut feeders, but do prefer sunflowers. Also drink in my pond.
This is the first year, I have a ground level window, hence nice angle for the shots through the window ...would be better to open the window next time for sharper results.
