• In praise of Turkey Vultures

    Remember that old Rodney Dangerfield line:  “I don’t get no respect?” The same could be said about Turkey Vultures, one of our most common Bay Area birds. So when we saw this post by a TV fan on the 10000 Birds blog, we had to share it with you. Taking a new look at a familiar bird seemed like a good way to start 2013.

    The Turkey Vulture (Cathartes aura) is probably one of the most misunderstood birds in North America.

    Some people think they are ugly, but not I.

    Their odd looks serve very important purposes. The adult Turkey Vulture’s head and distal neck is reddish bare skin with blackish bristles, which not only helps keep their heads clean when partaking of a carrion meal, but they also use that featherless head to help regulate body temperature.

    They can tuck their bare heads into their feather-collared necks to help keep warm, and when they are heat-stressed they will increase blood flow to the head, neck and legs, which dissipates heat by evaporative cooling.

    Of course they also help regulate their body temperature using their famous spread-winged postures. This is the “extended spread-wing posture”

    Turkey Vulture

     

    usually used to warm up in the morning sun or dry the wings, but sometimes it seems, just for fun.

    Then there is the “delta wing posture” when Turkey Vultures face the sun and often preen.

    Turkey Vultures are known for eating carrion but what some people don’t realize is that, unlike most birds, they have an excellent sense of smell. Because of their extra olfactory powers, many other carrion-eating birds like hawks, eagles and other vultures follow Turkey Vultures to kills.

    This juvenile bird can be identified by its gray head and black-tipped beak.

    A little bit later the juvenile gets comfortable, probably with a full crop.

    At another carcass, weeks earlier, there were several vultures attending a roadside kill…

    Can you imagine how many rotting animals we would have on the roadsides if we didn’t have vultures cleaning them up for us? I think Turkey Vultures deserve a lot more respect from us humans and especially birders.

    How many times have you been birding when someone thought they spotted a hawk, eagle or other raptor and then acted disappointed when they discovered it was “only a Turkey Vulture.”…

  • A 2014 resolution – buy shade-grown coffee

    By Scott Weidensaul 

    Migratory birds—which must overcome so many natural challenges as they journey from one end of the globe to another—are having a much harder time overcoming the obstacles that humans have added to the mix: habitat loss, environmental contaminants, climate change, and a lot more.

    But we humans can be helpful, too. I saw vivid proof of that last January in the highlands of northern Nicaragua, where declining migrants such as Wood Thrushes spend the nonbreeding season. For years, this area has been a stronghold for farmers growing quality shade coffee. Not coincidentally, it’s also known as a paradise for birds.

    An island of fertile green

    Everywhere we looked, we saw migrants: Philadelphia, Warbling, and Yellow-throated Vireos; Tennessee, Chestnut-sided, Wilson’s, and Yellow Warblers rolling through the understory in constant, flickering motion; Western Kingbirds and Western Wood-Pewees hawking insects in the treetops; Summer Tanagers and Rose-breasted Grosbeaks mixing with resident species like Black-headed Saltators and Clay-colored Robins. Flocks of Baltimore Orioles descended on blossoming trees and plucked the brilliant yellow flowers, dropping showers of blooms as they drank the rich pockets of nectar they’d revealed.

    Later, in the village of San Juan del Río Coco, I met with members of a cooperative of more than 400 small coffee producers who raise more than 2.5 million pounds of shade coffee every year. These producers raise coffee the way it’s been farmed for centuries there, below the canopy of intact, functioning forests that provide critical habitat for scores of migratory bird species. When these shade coffee farmers prosper, the outlook for migratory birds gets brighter, too.

    Seen from space, though, the hills around San Juan del Río Coco are an island of fertile green surrounded by hundreds of square kilometers of land already converted to sun coffee, pasture, and grain fields.

    Increasingly, small shade coffee farms have been destroyed to make way for sun-tolerant coffee—an industrialized, chemical-dependent system that renders what had been prime bird habitat into the ecological equivalent of a parking lot. By some estimates, more than 40 percent of the shade coffee farms in Latin America have already been lost to satiate the demand for cheap coffee.…

  • SF Christmas Bird Count sets record

    By Ilana DeBare

    What a glorious day for a count! It started out cool and windy, especially for the teams by the ocean, but by midday the sun was strong and hats came off.

    And best of all… we set a new record for the San Francisco Christmas Bird Count.

    Eighteen teams counted a preliminary total of 179 species — breaking the prior SF CBC record of 177 species and surpassing this year’s Oakland CBC total of 177. (Not that San Franciscans are competitive, of course — not in the slightest.)

    “It was a remarkable day. I’m anxious to see the total numbers we ended up with,” said CBC co-compiler Dan Murphy, who together with co-compiler Alan Hopkins will now collect and tally final numbers.

    Some preliminary findings from the count, as reported at the festive CBC dinner at the Log Cabin in the Presidio:

    • The only remaining California Quail found in the 15-mile-wide San Francisco count circle were at the Pacifica archery range.
    • Two Clapper Rails were found at Heron’s Head Park.

    • The team covering eastern Golden Gate Park set a new record of 70 species in its territory and had a “seven warbler day.”

    • The Sunset team counted 1,900 Red-throated Loons along the beach!
    • The Lake Merced team counted 40 rarities from six species that are not usually found in San Francisco, including Tree Swallows, White-throated Swifts, Great-tailed Grackles and a Tropical Kingbird.
    • The McLaren Park team – one of the teams with a particular challenge since their territory was landlocked, without water birds – found 55 species including four woodpecker species.
    • The Presidio team encountered some 3,000 gulls at a massive herring run at the end of the day.
    • The team with the highest count for the day was the Candlestick area team with a whopping 113 species, edging out the Presidio which had 104.

  • Remembering Rich Stallcup

    By Mike Lynes, GGBA Executive Director

    Amidst the excitement of the Oakland Christmas Bird Count on Sunday, we were saddened to hear news that Rich Stallcup had passed away from leukemia the previous evening.

    Rich was one of the leaders of Bay Area birding and ornithology — helping found the Point Reyes Bird Observatory and educating countless fledgling birders and naturalists through the years.

    I had the privilege of meeting Rich when I worked at the Point Reyes Bird Observatory, the organization that Rich helped found in the late 1960s and that he contributed to throughout his life. Rich was always generous with his time and knowledge and enjoyed educating a new generation of naturalists and birders. Many of us starting out as biologists at PRBO benefited immensely from his guidance and example.

    Oakland count compiler Dave Quady opened the CBC dinner on Sunday night with a tribute to Rich. Dave noted that Rich’s life was dedicated to enjoying birds and sharing that joy with others. Getting outside for bird walks and Christmas Bird Counts — and sharing those experiences with new people — are perhaps the greatest ways we can carry on his legacy. Everyone in the room then stood for a moment of applause and honor to Rich.

    GGBA board member John Muir “Jack” Laws posted this personal note about Rich on PRBO’s memorial page:

    While I was working on my Sierra field guide, I visited Rich with a pile of illustrations. He patiently went through them with me pointing out the subtlest corrections and suggested changes. As he did his stories began to flow as drawings triggered memories and anecdotes. He shared his knowledge, encouragement, and joy. Rich was deeply committed to conservation. I think that came from his love of nature that was regularly refreshed with time in the field. He fostered that love and stewardship in many of his students. We will miss you dear friend.

    We at Golden Gate Bird Alliance are extremely saddened by Rich’s loss, and we extend our condolences to his family and friends.

    If you would like to share your memories of Rich, please visit PRBO’s memorial web page at http://data.prbo.org/tools/guestbook/RichStallcup.html .

  • Oakland Christmas Bird Count finds 177 species

    Sunday December 16th was Golden Gate Bird Alliance’s 72nd annual Christmas Bird Count in Oakland. About 200 volunteers fanned out in a 15-mile circle, from the Oakland Airport in the south to Point Isabel in the north, and from Lafayette Reservoir in the east to Treasure Island in the West. Here is the initial report by Dave Quady, who organized the count with Bob Lewis. They will have a final report in several weeks.

    ————-

    By Dave Quady

    About 200 birders covered the Oakland CBC count circle yesterday in far better weather than predicted a few days earlier, and they recorded 177 species (preliminary count), right around our recent average.

    For the first time that I can recall we missed NO regularly occurring species on count day.  But we’re still interested in hearing about any unusual species found within the Oakland CBC circle during count week (Thurs Dec 13 through Wed Dec 19).  Please send me an email with details if you see, or have seen, a noteworthy species.

    On Sunday, observers reported these unusual species:

    • Snow Goose: near the soccer fields along the frontage road at Eastshore State Park, Berkeley
    • Ross’s Goose: one on the infield at Golden Gate Fields, and one at Arrowhead Marsh

    • Long-billed Dowitchers: at San Leandro Bay, identified by call
    • Short-eared Owl: one near the Bay Bridge Toll Plaza, and presumably a second bird at Arrowhead Marsh
    • Tree Swallows: a few over Lafayette Reservoir were the only swallow species reported
    • Black-and-white Warbler: between Albany Hill and the Ranch 99 (Pacific East Mall)

    • Hermit Warbler: one visiting a feeder on Yolo Street in Berkeley, one in the Tilden Park Botanical Garden, and one on Vollmer Peak
    • Clay-colored Sparrow: at a feeder on Deakin Street in Berkeley, photographed when it appeared about a week ago and also on Count Day.  At the compilation dinner it was chosen as the count’s Best Bird.
    • Swamp Sparrow: at Lafayette Reservoir near the visitor center, as George Griffeth reported to EBB Sightings yesterday
