Hello. I hope someone can help me! On facebook recently I found a post that had a picture of an eagle, perhaps a bald eagle, attesting that they have 340 degree vision. When I said that can't be true, people said it is, and, "google it". So I did google it:
There seem to be many many pages that are based on the 'all about vision' page above, from 2013,, including wikipedia as shown. This 340 degree vision claim has to be wrong!? I emailed the person who wrote the 2013 all about vision page above sending her this diagram.
She replied helpfully that she would be happy to try to correct the 2013 page, but that she needed an authoritative source to reference. So my question is, please can anyone direct me to an authoritative source (that can be pointed to on the internet) that states clearly and correctly how large an eagle's field of vision is? It's amazing to me how many of google's first large results are wrong, incidentally. Thank you in advance for any help that can be given. I look forward to replies.
UPDATE: I have been pointed to a couple of papers have figures between 73 and 83 and 100 degrees for Harris's hawks and black kites and short-toed eagles respectively, which is great, but more would be gratefully received! Thank you!
