Join the Advanced Birding Club (ABC) of Tahoma Audubon and the Slater Museum of Natural History at the University of Puget Sound for a presentation by curator and Professor Emeritus of the University of Washington Burke Museum, Sievert Rohwer.

Sievert will discuss his inside view of molt and what we don’t know about it. He will review his work that feather regrowth can’t be hurried, with the main differences between molt strategies having to do with how many feathers are molted at the same time: Simple (one at a time), Complex (various strategies including stepwise), and Simultaneous, with most feathers molted together.

He will start with an addendum to the earlier talk in December 2015 by reviewing new data for Golden Eagles showing that rectrices are replaced by need, rather than in a set sequence. This molt migration talk will review this issue in western passerines and consider possible effects of habitat changes due to irrigated agriculture on the decline of some western breeders.

Seating for this event is limited, so purchase your tickets early. Onsite registration may be available if space is available. A portion of the ticket proceeds will benefit Tahoma Audubon.

DirectionsTurn into the parking lot at N 14th and N Union in Tacoma at the University of Puget Sound campus. Thompson Hall is on the north end of the lot, and the lecture will be held in room 175.
