I’ve done some further looking into the raptor I saw over the courtyard pond at work today. Based on the field marks I saw and the shape of the bird, the closest match I can find is the White-tailed Kite. I didn’t notice the eye-color, but the white body and wings with some black near the leading-edge underwing matches little else. My perception of the size was a bit larger that what a White-tailed kite is described as, but size is sometimes hard to guage in the field.
I am not certain if I should count this as a positive ID or not. If so, it’s a lifer for me and the 98th bird species this year. I am not sure what to think.
