The differences I described for Canada Geese in a post here <a href="http://www.sibleyguides.com/2009/10/ageing-canada-geese/" rel="nofollow">http://www.sibleyguides.com/2009/10/ageing-canada-geese/</a> should work just as well for Pink-footed and other species. By December most young geese have molted some of the upper flanks, so you'll also see a contrast between broader, darker, more contrasting feathers there alongside the paler/faded, more rounded juvenile feathers on the belly. All that said, I see from one posted photo that the Kansas bird looks more like an immature dark morph Snow Goose - an understandable mistake. Pink-footed should have a dark brown head and neck, warm brown on the breast, etc. Hi Brandon, All geese can be aged at least until mid-winter by feather shapes.

Do you have a plate worked up that you could share with us?

Thanks very much for posting all this. I was not aware of any color difference but it looks like you have documented it pretty thoroughly. Hi Richard. Thanks very much for posting all this.

Young Thu, 18 Aug 2011 16:39:41 +0000 http://treeman1.wordpress.com/?page_id=6#comment-87079 I ask you to consider my interpretation of a novel observation (NECO extended gular sac coloration) that I have posted on my website: http://www.richbyoung.com/text-gular-id.html When I posted these images, numerous birders emailed me saying they had never seen nor heard anything in the literature regarding the NECO pink coloration and its ramifications. I discovered NECOs in Northern Utah for the first time in April 2009, http://www.utahbirds.org/RecCom/2010/2010_21Summary.htm , and twice again in 2010, http://www.utahbirds.org/RecCom/2010/2010_23Summary.htm , http://www.utahbirds.org/RecCom/2010/2010_20Summary.htm I found a stable population of 7 NECOs in the Salt Lake Valley at a permanent site that I studied over a 4 month period (May 2 through Oct. 18, 2010). Being retired, I spent over 200 hours studying these birds, with my main emphasis being photo-documentation. Among other things, I was struck by the unique ‘social signaling’ done by the NECOs available to me; specifically when I observed the pink coloration of their gular sacs when extended. Early on I noted there were major differences between NECO/DCCO extended gular sacs. Taking this a bit further, I saw the possibility that, using examples of birds’ (NECO/DCCO) gular sac coloration and morphology, I might have stumbled on a feature that could help clarify the I.D. issue among DCCO/NECO juveniles. I also believe that, the unique NECO extended gular sac coloration and morphology have been overlooked in the literature thus far. Any consideration of the above would be sincerely appreciated.

The maps in the books were last revised in 2002 (by Paul Lehman) so your Green Violetear did not make it in time. I'll add it to the next revision. Hi Kim, Thanks for your note.

We had the honor of hosting this wonderful bird at our feeders in our yard. This was in 2003 for 55 days. We turned it in and had the WVDNR and record people out to see the bird. Paul Lehman also came and viewed the bird. We had over 300 people come for the bird. Live in a gated area or we would have opened it up to more people. Of all those people only one birder was a sour birder. He lives in Kingwood WV of all places.All the other birds and clubs were very nice to meet. We even got some neat gifts bird feeder, books, bags sugar,candy. I have lots pictures and hours of video. We enjoyed talking wiht some really special people about birds. Even had two federal bird bander here one day. They were unable to catch him. We keep our eyes out each year for one to return.

Being able to understand the birds in your back yard, your camp site, or on your nature walk, is the key to having a great appreciation of life. Birds bring so much to help people stay connected to the earth! Your beautiful guides and descriptions are very welcome additions to the world of birds.

I recently acquired two of your books and they are the best I have ever seen. It is so helpful to see birds especailly the birds of prey in their different phases and flight patterns. Billy David
