<div dir="ltr"><div>Tim and Tweeters, I can't answer for the eBird reviewers, but in my opinion any species debate should be short, and you should go view the Brady Loop Common Crane. I agree that the amount of "whiteish" on the back of the head of the Brady Loop bird is more than many adult Common Cranes as can be viewed on Macauley (but <a href="https://macaulaylibrary.org/asset/519813611" target="_blank">this photo</a> of the Brady Loop bird shows the general outline of this plumage matching pretty well). However, it is not hard to find examples in Macauley of Common Cranes that match the Brady Loop bird pretty darn well, including <a href="https://macaulaylibrary.org/asset/520593571" target="_blank">here</a> (no extensive red patch, apparently lighter black roward rear of head). There are several other examples to be found from Eurasia showing that Common Cranes can show highly variable amounts of red on the top of head, white on the face and differing extents and shades of blackness on the back of head into neck. Also, Common Cranes achieve adult plumage by "late winter" so there is a possibility that this is a "nearly adult" plumage bird, but I don't think there's a need to call it a "possible hybrid" unless and until it changes plumage to match our expectations.</div><div><br></div><div>The correct and academic approach is to rule out other species and hybrids, but when a bird matches so well except some slight plumage variance from the average crisp European adult - and when a bird shows no other semblance of the other possible hybrid parent (Sandhill Crane) - see previously documented hybrid <a href="https://media.ebird.org/catalog?mediaType=photo&sort=obs_date_desc&taxonCode=x00657" target="_blank">here</a> - I think it's pretty clear, absent checking its DNA, that it is a Common Crane. But we don't check the DNA of all rare birds.</div><div><br></div><div>I have a major interest, since I just left on my first out-of-state trip in years when the last Common Crane showed up, so I missed it. . . BUT that aside ;) - I still feel strongly that we shouldn't trip ourselves up too much on the Brady Loop Common Crane.</div><div><br></div><div>Yours,</div><br clear="all"><div><div dir="ltr"><div dir="ltr">--Jordan Gunn</div><div>Edmonds, WA</div></div></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><br></div></div></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jan 4, 2023 at 5:04 PM Tim O'Brien <<a href="mailto:kertim7179@yahoo.com">kertim7179@yahoo.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello tweets,<br>
<br>
I am debating whether to make the trip to see the Common Crane on the Brady Loop. I am watching eBird and have noticed that none of the sightings have been confirmed by a reviewer yet. Is there a debate on the whether this is a pure Common Crane or is it a hybrid? If you don't want to share in public, please email me directly. As some of you know, the Brady Loop is my old stomping grounds and this bird would be great to add to my list.<br>
<br>
Thank you!<br>
