Did you notice that hummingbirds were scarce in Pittsburgh from early June to late July? They were here but they were busy nesting and hunting for insects instead of nectar. They reappeared in the last week of July, bolstered by a new population of juveniles.

This mob of ruby-throated hummingbirds visited a feeder in Atlanta, Georgia on 4 August. …

Here’s a tree full of hummingbirds in the southern California desert on 29 July. Likely species are black-chinned, Anna’s and Costa’s. …

… and here’s a slow motion video in the same southern California backyard.
