I’m hoping it’s cyclical - I’ve had more Cowbirds and Red Winged Blackbirds this year than normal too, now that you mention it.

For me, Goldfinches come and go throughout the season.

I’ve only had a few Hummers and the Orioles are pretty much gone now - busy nesting and raising babies, eating bugs and berries - don’t need the Grape Jelly right now.

If you can change up the seed-type you’re offering, that may bring back more Chickadees:

The weather plays a part, too. For me, we had a very cold May, and now it’s gone straight to hot and humid. That effects birds and they’re probably looking for food sources that also have a near-by natural water source, beyond the birdbaths we offer in our yards.

I might also add that there are an incredible number of blue jays in the area too.........

They're on my hit list after I saw one trying to get into my chickadee nest box and kill the last remaining fledgling about 3 years ago......
