Red-shouldered hawk screams, and the jays that copy them
When: March to April
A pair of red-shouldered hawks calls a loud, clear two-note scream again and again during courtship flights, and Mass Audubon says blue jays can mimic it almost perfectly. Mass Audubon's own trail guide says that if you are lucky you may hear one from the Overlook on the Tidmarsh All Persons Trail, and that they are especially noisy in March and April.
Why this time of year
Mass Audubon's atlas account says courtship runs through March and April, most often in mid-March, and that the calling stops once eggs are laid; most eggs are laid from early to mid-April, and some pairs in eastern Massachusetts may have eggs by late March. So the loud calling may tail off as April goes on.
How to notice it
- Follow the stone dust All Persons Trail at Mass Audubon's Tidmarsh Wildlife Sanctuary to the Overlook, where the path turns to wooden planks and there is seating on three sides, and listen for a loud, clear, two-note scream repeated in a series above the treetops.
- When you hear it, look up: the guide says the hawk may be perched or flying high above the canopy, and Mass Audubon's atlas says pairs call during aerial courtship displays.
- Try to see the bird before you decide. Mass Audubon notes that blue jays can mimic this call almost perfectly.
- Come back in May and notice the quiet: once a pair has eggs, the calling stops and the birds keep a low profile for the rest of the season.
Try this with kids: Close your eyes at the overlook and raise a hand every time you hear the hawk call from the sky.
Phrase to know: A “courtship display” is the flights and calls a pair uses to bond before nesting.
Safety
- Mass Audubon says Tidmarsh trails are not maintained during winter weather, so surfaces and footing may be slippery.
