Excellent. Well done.
Sharp, catchlight in the eye. The shallow DoF works for me.
The only thing I'd suggest is to see if maybe you could recover some detail in the tail (if, of course, it was there to start with).
There is one of those old sayings here that, "One swallow doesn't make a summer". Well, I saw my first swallow yesterday. That's them starting to arrive back from Africa.
The big worry is that everything is so delayed by the awful winter that we've had (gardeners reckon they're about 5 weeks behind where they normally would be), that birds will struggle once breeding gets underway.
Beautiful image, Bill. You nailed it wonderfully.
Beautiful photo...
