I think that a Kittiwake has a greater chance of occurrence now than a Boni in
Milwaukee. Bonis are very cold sensitive and leave the state mostly by the end
of Nov. Even when we had a large warm water plume emitting from the Jones' Is.
sewage filtration plant and they fed here daily into Dec. they readily left
when faced with cold weather like we have had in the last 3 weeks such that
they are essentially absent historically from Milwaukee in January.

The black collar on first-cycle Black-legged Kittiwakes can be readily missed
depending on the distance, lighting, and angle of bird's flight. On the other
hand, many first-cycle Bonaparte's Gulls can show a dusky color that highly
resembles that of kittiwakes, especially earlier in fall, so this feature alone
is not entirely reliable.
