SCCF: Red knots return to islands for winter
The Sanibel-Captiva Conservation Foundation reported that the wintering season for shorebirds is in full swing, and many species are spending their time resting and foraging on the islands. While some are uncommon, beach-goers are sure to spot a common, somewhat permanent species: the red knot.
The red knot is a rotund yet well-proportioned shorebird, similar to a short-billed dowitcher. It bears a terracotta-colored plumage during breeding season and, like most shorebirds, molts into a non-distinct gray-and-white plumage for the winter. Overall, its populations across the globe have been declining due to habitat loss, human disturbance and declines in prey availability. Habitat loss especially affects red knots due to the necessity of migratory stopover spots. Some knots fly 9,000 miles or more to their wintering and nesting grounds, so they need lots of good habitat along the way to regain their energy.
Some red knots are banded by researchers to track movement and survival of adult populations. Recently, there have been sightings of two knots that were banded on Sanibel in 2007. Red Knot TJ4 was spotted on Sanibel and Red Knot CE4 was found at Bunche Beach. TJ4 has not been observed on the island since 2010; CE4 has not been seen as far south as Sanibel and Bunche Beach since 2013.
The public can help the birds have a safe and successful winter by keeping dogs leashed, never chasing or feeding wildlife, picking up trash, and giving them plenty of space to rest and forage on the shores.
