SUMMARY:Putah Creek at the Kusch Gardens - TRIP IS FULL
DESCRIPTION:Black-chinned Hummingbird ©Manfred Kusch \nTrip Leader: Manfred Kusch \nDescription: TRIP IS FULL \nTour Manfred Kusch’s birding gardens between Davis and Winters. Kusch has cultivated his home garden and surrounding area\, which borders Putah Creek\, into a true birding extravaganza. He attracts a wide variety of birds in the gardens and habitat around the house\, especially hummingbirds and orioles. The multi-layered vegetation on either side of the creek hosts a variety of spring migrants\, including grosbeaks\, tanagers\, warblers\, and vireos. \nAccessibility: \nThis trip will involve some walking around in the Kusch gardens\, along with a stroll along well-maintained trails paralleling the creek. Most of these are flat\, but there are small slopes in a few spots. There will be frequent stops to look for and photograph birds. \nMeeting Location and Registration: \nBirders of all ages and skill levels are welcome! Please bring binoculars\, a camera and scope if you wish\, water\, and snacks. High winds or significant rain will cancel this trip. This popular event will be capped at 12 participants\, so sign-up early! \nPlease contact Zane Pickus with any questions or to sign-up at yolobirdalliance@gmail.com \nYolo Bird Alliance field trips are free and open to the public. \n

SUMMARY:Capay Open Space Park - Lesser Nighthawks
DESCRIPTION:Lesser Nighthawk ©Zane Pickus \nTrip Leader: Zane Pickus\, Bart Wickel\, Julian Johnson \nDescription:  \nNighthawks are a family of cryptically colored\, primarily nocturnal bird species that are a favorite of many birders. Cache Creek is the summer home of the Lesser Nighthawk\, which winters in Central and South America before returning to California to breed. Lesser Nighthawks primarily feed on insects under the cover of darkness\, but in the spring they routinely engage in dusk courtship rituals. Sunset at Capay Open Space Park is the perfect place to observe nighthawks as they chase each other in acrobatic flights and sing their eerie trilled songs. \nYou can learn more about Lesser Nighthawks and listen to their song here:\nhttps://www.allaboutbirds.org/guide/Lesser_Nighthawk/overview \nJoin Yolo Bird Alliance in a dusk birding trip to Capay Open Space Park. While this trip will be focused on the nighthawks\, there should be plenty of other birds to see. California Thrashers\, though inconspicuous\, nest here. Western Meadowlarks\, California Quail\, and a variety of swallows will be abundant. Given the date\, we could encounter a neotropical migrant or two! \nAccessibility: \nThis trip will involve some walking around in the Cache Creek floodplain\, which is mostly even ground but includes loose gravel and branches. Much of the trip will involve standing and listening for birds\, while also angling the group for nighthawk photo-ops. Restrooms are available in the Capay Open Space Park parking area. \nMeeting Location and Registration: \nBirders of all ages and skill levels are welcome! Please bring binoculars\, a camera if you wish\, water\, and snacks. High winds or significant rain will cancel the trip. This popular event will be capped at 15 participants\, so sign-up early! Our Davis meeting location will be shared once an RSVP has been made. Carpooling may be available but will be arranged day-of\, and all ridesharing will be private agreements between drivers and riders. \nPlease contact Zane Pickus with any questions or to sign-up at yolobirdalliance@gmail.com \nYolo Bird Alliance field trips are free and open to the public. \n

SUMMARY:Speaker Presentation - Mechanisms of Hummingbird Aggression
DESCRIPTION:  \nRufous Hummingbird ©Tom Uslan \nPROGRAM DESCRIPTION \nHummingbirds look delicate\, bright and inspiring\, but contrary to popular beliefs\, they are extremely aggressive animals that fight to defend territories and access mates. The public is invited to the Yolo Bird Alliance’s at its last monthly general meeting of the season on May 20\, 2026\, featuring Paulina L. González-Gómez. In this talk\, Paulina will focus on her research which explores the biological mechanisms behind male aggression\, from behavior to physiology. Male hummingbirds often use specialized “bill daggers” – sharp tips on their beaks – to attack rivals during high-speed chases. Their research studies how behavior and traits such as wing size and body mass influence birds’ territorial defense. In addition\, they investigate the role of hormones like testosterone in the development of bill weapons. They aim to learn how traits interact by linking field observations with hormone and morphology data. Our work is developed in tropical and temperate environments to understand how competition shapes evolution and behavior in one of the most extreme groups of birds. \nPaulina will present\, “Mechanisms of Hummingbird Aggression”\, in-person at the Davis Senior Center located at 646 A Street in Davis on May 20\, 2026. Additionally\, this meeting will be on Zoom; instructions for joining via Zoom\, follow. The meeting begins at 7:00 p.m. and ends at 8:50 (8:30 Zoom) p.m. People attending in-person are welcome to mingle following the conclusion of the Q&A portion\, until 8:50. \nSPEAKER BIO \nPaulina L. González-Gómez is an integrative biologist and evolutionary ecologist specializing in hummingbird biology and avian physiology. Her research focuses on how animals cope with environmental variability over the course of the year. She uses hummingbirds as a model system to study adaptive timing\, energetic balance\, and the coordination of life-history stages such as migration\, breeding\, and molt. At the University of California\, Davis\, Paulina teaches ecophysiology and scientific writing\, mentoring students in both field biology and effective science communication. \nThis event is free\, and you do not need to be a member of Yolo Bird Alliance. But if you would like to join\, visit https://yoloaudubon.org/join-renew-donate/. \nThe Yolo Bird Alliance fosters an appreciation of birds and other wildlife through educational programs and field trips\, brings conservation issues to public awareness\, and acts to preserve Yolo County bird life and habitat.
