Dear Birders, You are invited to the next LA Birders webinar: Insights into Population Trends of Swainson's Hawks and Songbirds With Brett Furnas, PhD Tuesday, May 16, 2023 at 7:00 PM on YouTube Dr. Brett Furnas, a quantitative ecologist with the California Department of Fish and Wildlife, will focus on recent population trends of Swainsons Hawks and several songbird species in California. As the Trustee state agency responsible for conserving wildlife and habitats in California, the Department of Fish and Wildlife routinely conducts field surveys to monitor population statuses of various wildlife species. Dr. Furnas will present his research on the increasing population for Swainsons Hawks, as well as trends for several songbird species, including the Olive-Sided Flycatcher, which breeds in montane forests. Dr. Furnas will also showcase how song dialects can be used to monitor avian diversity within a species, using the Hermit Warbler as an example. Please join us to learn more about how grassland and montane species are doing in California. This webinar will be livestreamed on our YouTube channel and will also be recorded for later viewing.

I should add that banding requires a long and rigorous apprenticeship not to be taken lightly. But observing the process will help you learn about molt. Sally M. Walters Sacramento CA toggle quoted message Show quoted text |
Bird banding or ringing as it is called in the UK is where you learn this. You can apply at Point Blue (Point Reyes Bird observatory in my day) for an apprenticeship. Im sure there are banding research programs in So Cal as well. Usually they all know each other. Even if you don't ever handle a bird observing is useful. Peter Pyle and Steve Howell are the authorities. Last comment if only human bones grew as fast as feathers! There are back yard banders but you need to find them. Sally M.

Aside from the resources already mentioned like the Pyle guide etc, the Birds Of The World site ( https://birdsoftheworld.org ) requires a membership for access, but has a section on molt for most birds in the ABA area. They also include overall molt timing (in the most general way, at a glance) in the wheel chart that shows timing of migration etc under Multimedia > Figures, for each species.

Hi Braxton- There are a number of resources (already mentioned) about understanding molt patterns - but if you want to learn about the why's of molt in an evolutionary and ecological context, the best resourceis the recently published "The Biology of Moult in Birds" by Lukas Jenni and Raffael Winkler. It's a European perspective, but we won't hould that against them. Ryan toggle quoted message Show quoted text |

I guess to be clear: My main interest is for a book that will help me be able to age most of the birds I see, and, secondly, explain the hows and whys of molt, and when they occur during the year. toggle quoted message Show quoted text |
The bible for this as I understand it would be the Pyle guide.

I justfound this book, based on reviews it seems like its by far thebest bookon the subject My only issue is finding one thats not $45+, but I may have to bite the bullet and buy it anyway.

Folks I am traveling and just heard about the massive number of Murphys Petrels seen by Lucas Corneliussen and team out of Bodega Way to go!!! Now the waters can be different in the Pioneer Canyon, but that will be the quest. To get out beyond the shelf and look for Murphys this Sunday out of Half Moon Bay. Right now the conditions look good to make this happen. We have a few spots left on the trip This trip will be guided by Chris Hayward, Malia DeFelice, Eli Gross, Dorian Anderson and Dessi Sieburth. You can sign up here: https://www.alvarosadventures.com/pelagic-dates-2023.html Click on the May 14 date to download more information about the boat and trip. Good birding.

Dear Birders, You are invited to the next LA Birders webinar: Introduction to Identifying Raptors in Flight: From Near to Far With Ted Keyel Tuesday, May 9, 2023 at 7:00 PM on YouTube Raptors are one of the most charismatic groups of birds, and a favorite to many birders and non-birders alike. Birds of prey often migrate along geographic features such as shorelines and ridges, and there are hawk watching sites across the country. Raptors include vultures, eagles, kites, harriers, accipiters, buteos, falcons, and owls. While diverse, there are a lot of similarities among birds of prey. Since observations are often at far distances and in poor lighting, they can be a very difficult group to identify. Join Ted as he provides a primer in how to separate raptor groups. This webinar will be livestreamed on our YouTube channel and will also be recorded for later viewing.

https://www.scientificamerican.com/article/people-differ-widely-in-their-understanding-of-even-a-simple-concept-such-as-the-word-penguin1/ I wonder how much the concepts discussed in this article (yes, you need to read the whole article) describe communication, miscommunication and friction between eBird users and eBird reviewers I'm not thinking of any one specific individual, rather, all of us.
