Guam kingfishers, or sihek as the birds are known by Guam’s indigenous Chamoru people, went extinct in the wild due to invasive brown tree snakes introduced to the island during World War II. A rescue effort was launched in 1980 to bring 28 sihek in the care of zoos, including Chicago’s Brookfield Zoo, with the goal of one day reintroducing the species back into the wild. Last August, 36 years later, nine sihek were flown to the Palmyra Atoll and placed in pre-release aviaries as a prelude to a trial reintroduction effort. One of those birds originated at Brookfield Zoo. Cody Hickman, the zoo’s associate director of avian care and conservation, will share the story and explain the zoo’s involvement.
Space is limited; registration is required with priority to Lake/Cook members. Email renabird3@gmail.com to register.
Park in the South parking lot and go to the South Gate entrance; zoo personnel will have a list of registrants direct you to the correct building. Free zoo admission.

The arrival of spring waterfowl is the first sign of spring for local birders as loons, pelicans and multiple duck species drop into Lake County lakes on the way north to their breeding grounds. Lake/Cook’s annual multi-stop spring waterfowl trip begins at Diamond Lake in Mundelein, with additional stops and directions provided at Diamond Lake based on leaders’ scouting to find the most productive sites. Dress warm, bring scopes if you have them, and get ready to greet what is usually dozens of Common Loons and American White Pelicans at one of our favorite inland waterways.
Directions: Meet at Gale Street Inn parking lot, 935 N. Diamond Lake Rd., Mundelein.

Texas Hill Country and Big Bend Led by Red Hill Birding
Texas Hill Country and Big Bend National Park are must-visit U.S. destinations for avid birders. Highlights include Golden-cheeked Warbler and Black-capped Vireo, two endangered migratory songbirds that breed exclusively in south central Texas; Colima Warbler, a montane species found nowhere else in the U.S.; and stunners like Painted Bunting, Painted Redstart, Lucifer Hummingbird, Greater Roadrunner and many more – plus the spectacle of millions of Mexican Free-tailed Bats leaving their roosting cave in a small town 90 minutes west of San Antonio in the evening.
Red Hill’s last trip here tallied 181 species, including the Elf Owl that was voted #1 bird of the trip. The lodge at Big Bend is scheduled to close for renovations at the end of the season, so this will be the last opportunity to make the trip for several years.
Email renabird3@gmail.com for a detailed itinerary and pricing. Space is limited; Lake/Cook members have priority.
