If you’re birding on the coast of Maine you already know this is a good year for winter finches, but since I’m from Pittsburgh I was surprised to hear jip-jip-jip among the conifers last Saturday in Acadia National Park. Was I hearing crossbills? Yes!
The Finch Network’s Winter Finch Forecast 2022-2023 explains:
In eastern North America, there is a good food crop along the coastal areas of Maritime Provinces southward into New England, which should hold many finches this winter.
Spruce cones are everywhere at Acadia, littering the trails in various stages of ripeness from sappy to seedless.
Small groups of red crossbills (Loxia curvirostra) are almost everywhere, too. If you know what to listen for the birds are easy to find on Mount Desert Island.
Lots of people are seeing and hearing them as shown in eBird’s September 2022 map below. However, the high density of crossbill reports is actually due to the high density of birders in the park.
On Sunday at Flying Mountain I saw eight red crossbills (Loxia curvirostra) eating spruce cones. This photo from 2013 shows how crossbills feed:
- Use feet to grab the cone,
- Use crossed beak to twist open the seed shield,
- Lick the seed out of the pocket.
The Winter Finch Forecast 2022-2023 predicts that points south along the coast will see crossbills this winter.
The “Northeastern Crossbill” (i.e. eastern Type 10) will be around this winter, but will they migrate down the coast to Long Island, Cape May and Delaware and points south, as they sometimes do as cone crops are depleted as we progress through the winter season.
Though Pittsburgh won’t see crossbills, check out the Winter Finch Forecast 2022-2023 for the species we can look forward to in western Pennsylvania.
