Subject: Winter movement of Killdeer
Regarding winter movements of shorebirds, Kenn Kaufmann has just posted on Facebook an interesting comparison of Killdeer in Bermuda.

Killdeer in Bermuda, first days of January 2018 <https://urldefense.proofpoint.com/v2/url?u=http-3A__ebird.org_ebird_map_killde-3Fneg-3Dtrue-26env.minX-3D-2D65-26env.minY-3D32.2-26env.maxX-3D-2D64.5-26env.maxY-3D32.4-26zh-3Dtrue-26gp-3Dfalse-26ev-3DZ-26mr-3Don-26bmo-3D1-26emo-3D1-26yr-3Drange-26byr-3D2018-26eyr-3D2018&d=DwICaQ&c=imBPVzF25OnBgGmVOlcsiEgHoG1i6YHLR0Sj_gZ4adc&r=ymRCw6Q-sBitug_rdeO1Tokz-I_SX2LQN2_Ocvlal9U&m=DNSMlbMUufVi9oq8x4Ki_1Ddf5ejVGOObXWjMXnzBZ4&s=Lw1143rqp1Zg7uLfBImEC6M0d98rpKomliVdGjlEIUw&e= >

He speculates this is due to the cold weather:
"Any that got offshore would have been picked up by the powerful wind
circulation around the intense storm that moved north off the Atlantic
Coast in recent days. Once the Killdeers were out over the water, many
probably just continued to fly downwind until they sighted Bermuda, and
many of them probably flew more than 800 miles southeastward before
winding up there. The phenomenon brings to mind accounts of another
plover, the Northern Lapwing, responding to extreme winter conditions in
Europe by making hard-weather movements westward to the coast and
beyond."
