Yesterday afternoon I checked our 10 Tree Swallow boxes. The most eggs I found in one box were eight, and the most chicks I found were eight!
Five chicks and two eggs,

Great divebomb shot! Interesting to see the nests, eggs, and chicks. Looks like you’re going to have lots more Tree Swallows around.
We love watching our tree swallows! Hubby found a baby on the ground that fledged a bit too soon and put it back in the nestbox. Parents had been frantic but all is calm now.
The “dive bomb” picture is exceptional!
Our tree swallows have left now. I don’t know how many babies they had. Hopefully they will comeback.
Tree Swallows are always very quick to leave after their young have fledged. If they had good nesting success this year, they will likely return next spring.
