I don't remember ever seeing a jay. We've had blue tits, but haven't seen one this year. We did see (what I think) coal tits (if they are tinier than blue tits).
We have robins in our garden, they tried to make a nest really low down, just outside our back door, so we had to block the cat flap. Luckily they decided to abandon that nest, as it was on a ladder, which we use regularly.
The robins are still here and are feeding from the food I put out under the trees. The blackbirds have also found this food.
We do have feeders, but starlings take the food from there, occasionally sparrows too. But the blackbirds and robins have never touched it and prefer the food on the ground.
Given up with the fat ball feeders, as no matter where they go, the squirrels manage to get them, then the pigeons scoop up the remnants.
We have a very large number of red kites, which are amazing to watch, but never come in the garden, only fly overhead.
I love the corvid family and would love to see a jay.
