This Week at the Park - April 25-May 2, 2025
Breeding pair of Tree Swallows

May has arrived, a little warmer and drier than you'd expect. The NOAA drought information system information for Kennett Square predicts the drought we've been in since last September will be lifted this month.

As I noted perviously the Green Herons have returned. This morning I saw not one, not two, but THREE Green herons in the tree they've been nesting in for the past three years.

The third heron was nearby, but uninvolved in nest building.

I know Green Heron's are typically solitary. Other heron species nest in colonies, but Green Herons do not. Could this be one of last year's herons that were born in this tree? Could this be some kind of cooperative breeding situation known in other birds but (so far as I can tell) not in green herons?

I'll keep watching and let you know.
