Dettagli dell'osservazione
I originally had this bird and these photos listed as a Loggerhead Shrike. Walter Marcisz via eBird wrote: "I have pasted comments from media reviewer Bill Rowe below. Bill believes your photo bird is a Northern Shrike, and I agree, as when your photos are lightened the Northern Shrike field marks become readily apparent. Try lightening your photos and see if you agree (if you are unable to lighten them, let me know and I can send you a lightened version). In any case if you agree the bird is a Northern Shrike, please change it and the record will be accepted. Bill Rowe's comments follow "I believe this is a Northern Shrike. Even as they appear in the list, the photos show a bill that is not stubby and has a strong hook at the tip. When I pull the two sitting-pose photos onto my desktop and magnify them and lighten the shadows, I see profuse fine barring on the underparts; a rather long bill with a pale-based mandible; a fairly narrow mask that does not fully enclose the eye (i.e., the upper part of the eye "bubbles up" above the mask) and appears to stop at the bill without extending over it. There is almost no apparent white along the upper margin of the mask, and also maybe none below the eye, but that's hard to be sure of even with lightening. In any case the other features make me feel sure this is a Northern."
