Every once in a while I try to help those who have birdwatchers on their Christmas lists by providing some ideas. I don't do this every year, but if you want to go back through some previous lists, here is the link to the 2009 blog post and the 2011 blog post. They are still perfectly valid and I promise your birding family members and friends will love the gift. Since both of these posts are extensive, I won't go back through all of the ideas, but instead focus on a few newer choices.
Although I have reviewed several books this year, here are my suggestions for some newly published bird books your birding friend may very well not have: The Warbler Guide and The Crossley Guide: Raptors. There are other fine books out there, but these two are a cut above.
If you have people on your list who are trying to improve their field birding skills, the Cornell Lab of Ornithology has some excellent webinars for a relatively low cost. They also have some other, more intensive courses that are more expensive. For a variety of learning opportunities, check out their website. I've taken some of these courses myself. A Cornell membership would be welcomed by most birders--the recipient would get a beautiful magazine as part of their membership and have the opportunity to participate in several citizen science activities if they are interested.
Wild Birds Unlimited in Wichita Falls also has some nice gifts: High quality T-shirts, books, binoculars, feeders and birdseed would be welcome gifts.
For the birder with everything, I would again recommend a donation to a birding organization. Wild Bird Rescue is always in need of monetary donations, especially to support their Avian Ambassador program. Who wouldn't want to sponsor a hawk or an owl?
Good luck with your Christmas shopping!
