Crossley Coffee Contest

Last month, we had a contest to celebrate the release of the Crossley ID Guide for Raptors. I asked readers to identify all of the Golden Eagles in a composite image, skipping none and including no non-Golden Eagles. The picture had a mixture of Golden Eagles, Bald Eagles, and a couple of other raptors.

Here are the answers:


As you can see, the answers are A, C, H and I.

If you want to know what the other birds are, you can look them up in the Crossley ID Guide for Raptors, which was the source for all of these images. Several contestants made the same mistake, the one we would expect: confusing an immature Bald Eagle with a Golden Eagle!

I think it is worth pointing out that I did not present, nor perhaps could I have presented, pictures of Golden Eagles that made them look very much like another raptor. In other words, there are few chances for a Golden Eagle false negative (where you see a Golden Eagle and identify it as a Red Tailed Hawk or an Osprey or something) but it is relatively easy to identify a non-Golden Eagle as a Golden (mainly by thinking an immature Bald Eagle is one).

The correct answers were by Chris Bortz, David Wade, and Dawn. These thee names were entered into a spreadsheet and associated with a psuedo-random number formula. The formula was then recalculated (F9) three times, and the results copies and paste-value’d into a new set of cells. The person with the highest random number was the winner, and the winner was Dawn.

Congratulations Dawn! I’ve send you an email.

    We mainly have red-tailed hawks around here (Clear Lake area). Years ago I took my boat from Seattle up to Canada and found a ton of bald eagles in the trees around Egmont. And Carol and I saw a bunch of osprey nests (and a couple of ospreys) five years ago while on the train from Vancouver BC to Lake Louise. No golden or bald eagles or ospreys down here.

    BTW, I understand that a lot of golden eagles are being killed by wind farms. Is that true?

    Not really. There is one poorly placed wind farm that has has a high kill rate. People who are against wind farms then extrapolated that kill rate to all wind farms and made up a false high number and have been spreading that around.
