I set the rollers up in the kitchen so I could see the birds on and around the feeder in the garden Anything's worth doing to ease indoor training hours.
Birds seen included blue & great tits, collared dove, jay, house sparrows, dunnocks, blackbirds, song thrushes, coal tit, and a wren. It's very easy to see where the term pecking order comes from. The podium of pecking order, in my garden at least, goes;
3rd Robin
2nd Starling
1st Greater Spotted Woodpecker. Basically nobody f***s with the woodpeckers when they're feeding.
A good session on the rollers. 90 minutes soon went by.
