Cross-country Birding adventure
Robert Raffel

Mount Diablo Bird Alliance will meet Thursday, February 1, in the Camellia Room at the Gardens at Heather Farm.

7:00 PM Announcements
7:15 PM Refreshments and Raffle
7:30 PM Main Program: Cross-country Birding Adventure
*as a conservation organization we encourage you to bring your own mug for coffee or tea
Last year at this time, Robert was sleeping in his car in sub-zero temperatures in search of Snowy Owls and other birds from the far north. At our February meeting, Robert will share the highlights of his six month road trip, which included birding along the Canadian border from Washington to Maine in January, birding Florida and the Texas Coast during spring migration, and then birding from Arkansas to Minnesota back to Oregon in the beginning of the breeding season. Robert has plenty of pictures of his favorite birds including some that show identification challenges and insights he encountered along the way. Robert’s presentation will also share his perspectives on birding various parts of the country as well as considerations to take into account in planning your own trip.
Robert Raffel grew up in Pennsylvania and began birding as a teenager. In his 30s, he started birding more seriously, traveling extensively throughout the continental United States, building his life list. In his 40s and 50s, Robert took a break from birding and focused on raising his two sons. Once they could drive and no longer needed his services, Robert picked up his binoculars again and found that eBird and digital photography had completely changed birding for the better.

Introducing the Birds of Heather Farm
2024-02-21 08:30 - 10:30 | Heather Farm Park, 301 N San Carlos Dr, Walnut Creek, CA, 94598, United States
A casual walk for birders of all experience levels, and especially beginners!
Wednesday, February 21, 2024, 8:30 – 10:30am
Heather Farm Park in Walnut Creek is an underrated birding spot, home to dozens of resident species and attracting many migrants as well! We’ll meet at the overlook of the Natural Lake, west of North San Carlos Drive about 100 yards beyond the community center.
At 8:30AM an experienced birder or two will be on hand to demonstrate how to properly use binoculars, and to discuss birding guidebooks and apps. We’ll begin scanning the lake too, to see which ducks and other birds might be in town for the winter. When we’re good and ready, we’ll set off on a walk around the lake and adjacent Nature Area—an easy stroll of about half a mile on mostly level, accessible trails. Along the way we’ll hope to see and hear sparrow, finch, woodpecker and warbler, along with nuthatch and dove. Wrens, thrushes, herons, and raptors are often found here too—though in birding, as in life, nothing is guaranteed! Our guides will explain what features on the birds to look for, to tell one from the other.
We should be done around 10:30. Birders of all experience levels are welcome! Binoculars will be available to borrow for those who need them. Trip will go on in gray weather, but rain or high wind cancels.
Free event, with pre-registration requested.

MDBA Field Trip -- Bodega Bay
2024-02-24 09:30 - 15:00 | Bodega Bay Trailhead, Bodega Bay Trailhead, Bodega Bay, CA, 94923
Why do we go all the way to Bodega Bay? To see loons close up – the Common, Pacific, and Red-throated species are all likely. To see Brant. To see Double-crested, Brandt’s and Pelagic cormorants side-by-side to strengthen your ID skills. This is a great place for birders of all levels and birders new to the Bay Area.
Due to the tide times, we’ll start at 9:30AM at Bodega Head – NOT our previous meeting point at the Tides restaurant. You might still want to make a rest stop at the Tides before continuing out to the Head, where there are only park-style pit toilets.
After birding Bodega Head we’ll work our way back along the western shore of Bodega Bay, with stops including the “Hole in the Head,” Campbell Cove, and Porto Bodega Marina. Somewhere along the way we’ll pause for a picnic lunch. In the afternoon we may continue to Doran Beach Road on the east side of the harbor. There’s a $7 parking fee at Doran Regional Park.
Be prepared for variable weather. Bring lunch, snacks, and liquids. There is a chemical toilet “porta-potty” at Porto Bodega Marina, pit toilets above the Hole in the Head, and restrooms with flush toilets at Doran Beach. For a comfort stop near the end of the drive out stop at Tides Wharf and Restaurant (on the shore side opposite the Inn at the Tides, 800 Highway 1), though the snack bar will probably be closed.
Hike Rating: 1 – Easy, with little elevation change
Leader: Maureen Lahiff, MLahiff@aol.com, 510-484-6529
Meet at Bodega Head, GPS: 38.30356934, -123.06467926

Take Hwy 1 to Bodega Bay. Just past “downtown” Bodega Bay turn left on Eastshore Road, and follow it down to Bay Flat Road and turn right. Bay Flat Road becomes the Westshore Road. Follow the Westshore Road all the way to the end, up the hill past Campbell Cove to the large parking lot. From Walnut Creek, it’s about a 2 hour drive.

7:00 PM Announcements
7:15 PM Refreshments and Raffle
7:30 PM Main Program: Birds of Palomarin
*as a conservation organization we encourage you to bring your own mug for coffee or tea
Larissa is a wildlife artist and biologist who works almost exclusively with birds. She has been working seasonal field jobs since she graduated from Dickinson College in 2020 and has found huge inspiration while out in nature! Her goal is to share her experiences in the field and bring the beauty of the natural world to her community through her drawings.
This piece was inspired by a recent apprenticeship at Point Blue’s Palomarin Field Station, where she learned about bird banding and conservation science. She was an apprentice for nearly eight months from February to October, and the season included the spring migration, breeding season, and part of fall migration. She and her fellow apprentices banded a total of 78 bird species during this time, each of which is represented in the drawing. The piece is meant to represent all aspects of the Palomarin banding program, including the plants that were studied at the sites and a variety of bird age classes. Completed in April 2023, the Birds of Palomarin, while being in part an educational piece, evolved into a way to thank everyone she worked with at Palomarin and show her love for the birds.

7:15 PM Refreshments and Raffle
7:30 PM Main Program: Bay Area Woodpeckers
*as a conservation organization we encourage you to bring your own mug for coffee or tea
Woodpeckers have captured the human imagination for generations. The distant sounds of pecking, flashes of red plumage, and inevitable disappearance into the shadows of the forest evoke a sense of wonder about these extraordinary yet elusive creatures. Jeffery Martin’s lecture and his close-up high-definition video segments explore the foraging strategies of our eight Bay Area woodpecker species. Insect excavation, acorn storage, the use of sap wells and other intriguing behaviors are our focus. Jeff’s video segments illustrate unique evolutionary adaptations. We examine the anatomy of feet, tail, tongue and head which enable agile vertical climbing, adept grabbing of prey, and protection from concussion and dust inhalation. From the exquisite green and rose-colored Lewis’s Woodpecker to the dazzling Northern Flicker, and more, we take a close-up look at the worlds of our eight North Bay Woodpeckers.
Videographer and naturalist, Jeffery Martin has filmed and produced “Bahia Wildlife Habitat” and “Birds of Las Gallinas Marsh” which can be viewed on the web sites of Marin Audubon Society and Las Gallinas Valley Sanitary District. His films, “Woodpecker Haven” and “Birds of Lake Solano and Putah Creek” have been shown at the Lake Solano Visitors Center and Solano Parks Website. His “Bay Area Woodpeckers” and “Foraging Behavior in Large Wading Birds” lecture/video programs have been presented at several Bay Area Audubon Societies. In the past, Jeff has contributed to the slide library, visitor literature and campfire talks for Pt. Reyes National Seashore. He has created an assortment of natural history walks, lectures and training for adults and children. In another vein, he has lectured to college faculty, students, and National Park Service Rangers on “visitor motivation” and the “psychology of nature” including on safari in East Africa. In his “day job” Jeff is a clinical psychologist and associate clinical professor at UCSF School of Medicine.

MDBA Field Trip -- Pine Canyon
2024-04-20 08:00 - 13:00 | Diablo Foothills Regional Park Trailhead Parking, 1700 Castle Rock Rd, Walnut Creek, 94598
This field trip is especially good for beginning birders! Pine Canyon, which includes the Castle Rock EBRPD recreational area, and the Diablo Foothills Regional Park just beyond, provides rich habitat and resources for spring migrants passing through, as well as for many returning and nesting summer residents.
We should expect to find nesting pairs of Bullock’s Orioles and House Wrens. Warbling Vireos, along with their cousins, the Cassin’s Vireo, nest within the canyon. Rufous-crowned Sparrows are to be found, and if we’re lucky, Lazuli Bunting. We’ll look (and listen) for Black-headed Grosbeaks and Western Tanagers. Western Wood-Pewees and Pacific-slope Flycatchers pass through. We might get lucky with an Olive-sided Flycatcher. And the warblers: breeding plumage Yellow-rumped, Black-throated Gray, Wilson’s, Yellow, Nashville, MacGillivray’s, Hermit, Orange-crowned, and Townsend’s.
Bring water and snacks. This should be a wonderful springtime field trip.
Trail Rating: Category 2–Moderate with creek crossings
Elevation change: 150-200 feet
Leader: Tracy Farrington, 925-788-6223

2024-04-24 07:30 - 14:00 | Putah Creek Parking Lot, Putah Creek Parking Lot, Davis, CA, 95616
This delightful, fairly short stretch of Putah Creek (~3/4 miles), can be very productive during Spring migration. It’s a fairly easy walk through lovely riparian right down in the creek bed. And the occasional sandy stretch will often host several species of birds bathing in the shallows.
Expect to find a nice selection of warblers: Yellow, Black-throated Gray, Orange-crowned, Wilson’s, MacGillivray’s, Hermit, Townsend’s, and perhaps a Nashville. And, of course, Pacific Slope Flycatcher, Western Wood Pewee, Western Tanager, and keep an eye overhead for a Swainson’s Hawk. Vagrants pop up from time to time (I found a Tennessee Warbler a couple years ago), so don’t discount the prospect of a nice surprise.
Bring water and snacks. There are no bathroom facilities.
Trail Rating: Category 1, an easy walk.

2024-06-01 08:30 - 15:00 | Kenneth C. Patrick Visitor Center, 1 Drake Beach Rd, Inverness, CA, 94937, United States
Point Reyes is one of the premiere birding locations in Northern California, a great spot to find rarities during migration—like the Prairie Warbler pictured above (image by Beth Branthaver). MDBA tries to visit at least twice a year. On our late-spring trip we hope to see northbound migrants as well as resident birds in their best plumage. The exact itinerary will depend on weather, but we’ll probably visit the lighthouse overlook, and the “fish docks” area. After lunch we may walk down the “Avenue of Cypresses” to the old RCA building.
Bring water and lunch as this area is remote.
Rating: Category 2 — some walking through grass under trees, and on paved roads with fairly significant grade and on paved roads. Elevation change: 100 ft
