SUMMARY:Christmas Bird Count 2022
DESCRIPTION:Northern Pygmy Owl\, \nPhoto by Bart Wickel\n\n\n\n\nThe 52st annual Putah Creek CBC is scheduled for Sunday\, December 18th\, regardless of weather.  \n\n\n\n\nTHE 2022 PUTAH CREEK CBC IS NOW CLOSED TO NEW VOLUNTEERS. \n\n\n\nOur annual pre-count and Bird ID workshop was held Dec 14th (watch the presentation here). The workshop consists of a primer on bird identification and a discussion of recent count trends\, including a review of climate change and forest fire impacts on the count circle.\n\n\n\nAlso join us Sunday\, December 18th for the Count Compilation at the Davis Senior Center\, Valente Room\, 646 A Street.  Doors open at 5pm\, potluck at 6pm and compilation meeting from 7pm – 8:30pm.   \n\n\n\n\nThe 15-mile diameter count circle is centered southwest of Winters\, California. It is divided into 10 areas and spans parts of Yolo\, Solano\, and Napa Counties. This interactive map shows the areas we cover and associated birding hotspots. \n\n\n\n\n  \n\n\n\n\n\n\n\nPutah Creek CBC Area Leaders\n\n\n\nSunday\, December 18th\, 2022\n\n\n\nOrganizer and CompilerBart WickelEmail BartPre-CBC Bird ID WorkshopZane PickusEmail ZaneArea 1: Lake Berryessa\, Thompson Canyon\, & Quail RidgeArea Leader: Bobby WalshEmail BobbyArea 2: Bray CanyonArea Leader: Ian TaylorEmail IanArea 3: North Side (Chickahominy Slough)Area Leader: Ryan JankeEmail RyanArea 4: Winters to Monticello DamArea Leader: Michael PerroneEmail MichaelArea 5: East Side (Putah Creek & Hwy 505)Area Leader: Kevin GuseEmail KevinArea 6: English Hills NorthArea Leader: Zane PickusEmail ZaneArea 7: English Hills SouthArea Leader: Cameron TescherEmail CameronArea 8: Mt.

In our 51 consecutive years of solid data collection\, we have been able to identify trends for several species and to relate them to conservation issues.  \n\n\n\n\nWe typically have about 80 participants\, making it one of the largest inland counts in California and the Central Valley.\n\n\n\nWe typically see over 140 species.\n\n\n\nWe have led the nation in Northern Pygmy-Owl\, Northern (Red-shafted) Flicker\, Nuttall’s Woodpecker\, Red-breasted Sapsucker\, Yellow-billed Magpie\, Oak Titmouse\, American Robin\, Lark Sparrow\, and Lesser Goldfinch counts. \n\n\n\nWe have provided important data on the effects of West Nile Virus on some species (especially Yellow-billed Magpie).\n\n\n\nWe have generated data useful for illustrating impacts of climate change and loss of grasslands.\n\n\n\n\nWrentit – Observed in Area 8 shortly before the LNU fire in 2020); © Bart Wickel\n\n\n\nIn 2020 during the “LNU” fire\, approximately 60% of the count circle burned\, including all (or nearly all) of Areas 1\, 2\, 8\, 9\, and 10\, and large sections of Areas 3\, 4\, 6\, and 7. In addition\, the Central Valley has been experiencing severe drought conditions\, with the period from 2020 to 2022 being the driest on record since 1896. While the counts in 2020 and 2021 revealed dramatic impacts on the bird populations\, we anticipate witnessing signs of recovery in 2022. \n\n\n\nIf you are interested in the history of Christmas Bird Counts\, this page on the Audubon website is helpful. Summary: instead of killing as many birds as possible during the holiday season\, we now count as many as we can. \n\n\n\n\n\n\n\n2021 Putah Creek CBC Summary\n\n\n\nBy Bart Wickel \n\n\n\nThe 51st Putah Creek Christmas Bird Count was held on December 19\, 2021. Area leaders sought to cover all usual routes with teams of experienced birders accompanied by new or less experienced birders. While the count was open to the public we adhered to a modified protocol due to covid recommendations\, which resulted in lower participation than in pre-covid years with 73 participants compared to the usual average of 85.  \n\n\n\nThe count was successful in covering all the usual routes with a combined 187 party hours during which we collectively traveled 110 miles on foot and 209 miles by car. Conditions were colder than usual and foggy\, especially in the early hours of the day. \n\n\n\nA new eBird feature that was introduced this year was the trip-report function. This allows the creation of a summary of all lists for a particular day\, which turned out to be particularly helpful for a Christmas Bird Count. While not all of the observations this year were covered\, we managed to get close to the count totals for most species. The day report can be found at: https://ebird.org/tripreport/26130 \n\n\n\nDuring this year’s count we observed unusually high numbers of waterfowl and gulls\, likely due to these foggy conditions. In contrast to previous years\, owl-counts were low.  \n\n\n\nAmong waterfowl\, record high-counts were observed for: Snow Goose (826)\, Greater White-fronted Goose (693)\, Green-winged Teal (449)\, Common Merganser (357)\, Lesser Scaup (25)\, and a first observation of a mute Swan on Putah Creek.  \n\n\n\nAmong gulls we observed record high counts for: California Gull (316)\, Herring Gull (54) as well as a first observation of two Glaucous-winged Gulls in two distinct locations.  \n\n\n\nMulti-year trends of increasing numbers of insectivores and fructivores\, correlated with warmer winters and a lack of overnight freezes\, seem to persist with continued high counts for Western Bluebird\, Anna’s Hummingbird\, White-breasted Nuthatch\, Sora and Virginia Rail. A record number of Common Raven (679) was also observed.  \n\n\n\nThe impacts of the LNU Lightning Complex megafire in August 2020\, which burned approximately 60% of the count circle\, are clearly marked by sustained low numbers of American Robin\, Wild Turkey\, Wrentits\, Canyon Wrens and an all-out absence of Pileated Woodpeckers.  \n\n\n\nThanks to all the area leaders for assembling thorough coverage under pandemic conditions. We hope next year we can invite all birders and birders-to-be and finish the day with the traditional potluck
