SUMMARY:The Evolution of the Flamingo’s Smile
DESCRIPTION:Presenter – Christopher Torres Phd\, Assistant Professor in the Dept. of Biological Sciences at the University of the Pacific \nChristopher Torres\, PhD\, Assistant Professor in the Dept. of Biological Sciences at the University of the Pacific\, will talk about “The Evolution of the Flamingo’s Smile”. Flamingos are among the most iconic birds on the planet – with their ostentatious coloration and perpetually inverted smile\, it’s easy to understand why they are featured in zoos (and front yards) the world over. Flamingos are also among the world’s most highly specialized birds\, employing an approach to filter-feeding utterly unlike anything else. As such\, flamingos provide an ideal model system for studying what drives the evolution of beak shape\, what drives birds to become increasingly specialized at the ever-increasing risk of extinction\, and how those shifts in ecology and morphology correspond to shifts in Earth history. \nBut flamingo evolutionary history remains shrouded in mystery\, being marked by enigmatic origins\, cryptic fossils\, and repeated brushes with extinction. In this talk\, Chris will share current understanding of that history\, and will tell several tales about how he and his colleagues are seeking to dispel many of those mysteries\, including: How\, after two centuries of study\, it was only relatively recently discovered that grebes are the closest living relatives of flamingos. How the understanding of what came before flamingos and grebes remains poor\, despite the existence of a nearly complete fossil documenting that exact moment in evolutionary time. How a lineage of bizarre\, prehistoric ‘straight-beaked flamingos’ managed to achieve a near-global distribution… and then vanished from the fossil record. \nHow the ancestors of modern\, ‘curved-beaked flamingos’ nearly met the same fate… before spreading back out across the globe. How California – along with the rest of North America’s West Coast – was covered in flamingos as recently as a few tens of thousands of years ago. How baby flamingos undergo one of the most unique post-hatching changes in beak morphology known among birds. And how watching those baby flamingos grow up might provide insights to the earliest stages of flamingo life.

SUMMARY:Beginner’s Bird Walk @ River Islands
DESCRIPTION:Join leader Henry Koertzen for a beginning bird walk for folks of all ages. We will start at the gravel parking lot at the south entrance of River Islands (at the river side of the road) . We will walk the smooth paved path\, accessible by a stroller or wheelchair.We will do a two mile loop. First we will follow the path along the San Joaquin River\, and then we will cross over to return around the lake. Note: there are no bathroom facilities at the site. \nDirectionsTake exit 460 (Manthey Rd) from I-5(S).Turn right onto Manthey Road.At the first stop sign turn left onto Stewart Road. When you reach the first roundabout the parking area is on the right. Coordinates 37.788505\, -121.309836\nhttps://maps.app.goo.gl/2jzoQsgQJcNVeDhf7

SUMMARY:Point Reyes National Seashore Trip
DESCRIPTION:Guide – Ralph Baker \nPoint Reyes National Seashore\, located in Marin County\, offers some of the finest birding in the United States. The park’s coastal location and its wealth of unspoiled habitats\, estuaries\, grasslands\, coastal scrub\, and forest attract many migrating and wintering birds. \n\nThe Point Reyes peninsula projects some 10 miles seaward from the “mainland” and acts as a sort of funnel. Many land birds travel south along the coast during fall migration and when they reach the end of the peninsula\, they see open water ahead of them and tend to stop and rest before heading “out to sea”. Many vagrants (birds that may have made errors in navigation and thus are unexpected in this area) pass through during September and October and the number of birds seen on or over the water from the fish docks can be astonishing. According to eBird\, over 73% of the naturally occurring bird species in California have been reported in Marin County! We’ll see how many we can find.\n\nThe precise locations we will bird will depend upon what is being reported in the days leading up to the trip. This will be an all-day trip\, so dress in layers\, as the weather can be unpredictable\, and wear comfortable shoes\, as we may do a considerable amount of walking. Also bring water\, lunch/snacks\, a scope (if you have one) and don’t forget your binoculars. Mosquitoes are not usually a problem and there are restrooms available. \n\n\n\nPlease RSVP to Ralph at sharks_hockey_maniac@yahoo.com \n\n\n\n\nDirections: Meet at 8:45am at the Bear Valley Visitor Center\, 1 Bear Valley Visitor Center Access Road\, Point Reyes Station\, CA 94956
