ERICKSON, LSA Associates, 20 Executive Park, Suite 200, Irvine, California 92614; [email protected] ABSTRACT: We report 56 bird specimens of 31 species taken on Isla Guadalupe, Baja California, between 1986 and 2004 and housed at the Colección Ornitológica del Laboratorio de Vertebrados de la Facultad de Ciencias, Universidad Autónoma de Baja California, Ensenada, along with other sight and specimen records. The speci- mens include the first published Guadalupe records for 10 species: the Ring-necked Duck (Aythya collaris), Long-billed Curlew (Numenius americanus), Bonaparte’s Gull (Larus philadelphia), Ash-throated Flycatcher (Myiarchus cinerascens), Warbling Vireo (Vireo gilvus), Tree Swallow (Tachycineta bicolor), Yellow Warbler (Dendroica petechia), Magnolia Warbler (Dendroica magnolia), Yellow-headed Blackbird (Xan- thocephalus xanthocephalus), and Orchard Oriole (Icterus spurius). A specimen of the eastern subspecies of Brown-headed Cowbird (Molothrus ater ater) and a sight record of the Gray-cheeked Thrush (Catharus minimus) are the first reported from the Baja California Peninsula (and islands). A photographed Franklin’s Gull (Larus pipixcan) is also an island first. Currently 136 native species and three species intro- duced in North America have been recorded from the island and nearby waters. -

Tropical Birding Trip Report Costa Rica: The Introtour | July 2017 A Tropical Birding SET DEPARTURE tour Costa Rica: The Introtour July 15 – 25, 2017 Tour Leader: Scott Olmstead INTRODUCTION This year’s July departure of the Costa Rica Introtour had great luck with many of the most spectacular, emblematic birds of Central America like Resplendent Quetzal (photo right), Three-wattled Bellbird, Great Green and Scarlet Macaws, and Keel-billed Toucan, as well as some excellent rarities like Black Hawk- Eagle, Ochraceous Pewee and Azure-hooded Jay. We enjoyed great weather for birding, with almost no morning rain throughout the trip, and just a few delightful afternoon and evening showers. Comfortable accommodations, iconic landscapes, abundant, delicious meals, and our charismatic driver Luís enhanced our time in the field. Our group, made up of a mix of first- timers to the tropics and more seasoned tropical birders, got along wonderfully, with some spying their first-ever toucans, motmots, puffbirds, etc. on this trip, and others ticking off regional endemics and hard-to-get species. We were fortunate to have several high-quality mammal sightings, including three monkey species, Derby’s Wooly Opossum, Northern Tamandua, and Tayra. Then there were many www.tropicalbirding.com +1-409-515-9110 [email protected] Page Tropical Birding Trip Report Costa Rica: The Introtour | July 2017 superb reptiles and amphibians, among them Emerald Basilisk, Helmeted Iguana, Green-and- black and Strawberry Poison Frogs, and Red-eyed Leaf Frog.

Appendix D5 Restore Seabirds to Baja California Pacific Islands
Appendix D5 Restore Seabirds to Baja California Pacific Islands Appendix D5 Restore Seabirds to Baja California Pacific Islands Appendix D5 Restore Seabirds on the Baja California Pacific Islands The Natural Resource Trustees for the Montrose case (Trustees) have evaluated a variety of seabird restoration actions for the Baja California Pacific islands in Mexico. These islands support a wide range of seabirds that nest in or use the Southern California Bight (SCB). Restoration efforts would target a suite of seabird species, including the Cassin’s auklet, Brandt’s cormorant, double-crested cormorant, California brown pelican, ashy storm-petrel, and Xantus’s murrelet. To streamline the evaluation of these actions, the general background and regulatory framework is provided below. Detailed project descriptions are then provided for the following islands: (1) Guadalupe Island, (2) Coronado and Todos Santos Islands, (3) San Jeronimo and San Martín Islands, and (4) San Benito, Natividad, Asunción, and San Roque Islands. The actions discussed in this appendix do not cover all of the potential seabird restoration actions for the Baja California Pacific islands; therefore, the Trustees will consider additional actions in the future for implementation under this Restoration Plan, as appropriate. D5.1 GENERAL BACKGROUND The Baja California Pacific islands are located in the northwestern portion of Mexico, off of the Pacific coast of Baja California (Figure D5-1). Of the 12 islands or island groups (18 total islands) in this region, nine present unique opportunities for seabird restoration. Three of these islands or island groups (Coronado, Todos Santos, and San Martín) are oceanographically considered part of the SCB. -
Costa Rica a Relaxed & Easy Tour
COSTA RICA A RELAXED & EASY TOUR NOVEMBER 2–10, 2019 Fiery-throated Hummingbird, Panterpe insignis. D. Ascanio.

We also enjoyed views of a pair of Rufous-naped Wrens, a vocal Rufous-browed Peppershrike, and the unmistakable Lesson’s Motmot. After breakfast, we took the road to Cartago where a little productive grassland allowed views of a few birds. Then we ascended the Pan-American Highway and, after reaching a higher elevation, we noticed a sudden change in vegetation and humidity; we had entered the cloud forest. A wonderful lunch was accompanied by excellent views of the territorial Fiery-throated Hummingbird and other allies including Talamanca and Volcano hummingbirds. Continuing our birding activities after lunch, we decided to take our chances exloring the highlands, to the antenna road. Reaching the pre-paramo is always a challenge because the weather can change dramatically in a few minutes. But, despite the wind and the humidity, we enjoyed very close views of Volcano Junco. Later, a Peg-billed Finch showed up for seconds, and for a grand finale we had a striking encounter with the Timberline Wren. -

Calle Moctezuma 836, Zona Centro, Ensenada, B.C., México, 22800. <[email protected]>. Abstract Feral cats (Felis catus) introduced to new environments have caused the extinction of many vertebrate species, including six species of birds on Guadalupe Island, México. To save species from extinction and restore natural processes, cats have been eradicated from islands using a variety of techniques. Eradication campaigns have to be planned carefully; ideally supported by information about the population to be eradicated. Our study focuses on home range estimation (fixed kernel); bait consumption by feral cats and non-target species; and diet of feral cats on Guadalupe Island. Home range was 76 to 1098 ha (KE 95) and core areas 21 to 196 ha (KE 50). Feral cats and non-target species including Guadalupe junco (Junco hyemalis insularis), Guadalupe rock wren (Salpinctes obsoletus guadalupensis), western gull (Larus occidentalis), and house mouse (Mus musculus) consumed baits. Items most commonly found in diet samples were mice (66.5%) and birds (16.8%). -
Costa Rica Custom Tour Trip Report
COSTA RICA CUSTOM TOUR TRIP REPORT 16 FEBRUARY – 5 MARCH 2020 By Eduardo Ormaeche Ornate Hawk-Eagle www.birdingecotours.com [email protected] 2 | TRIP REPORT Costa Rica: February 2020 Overview Our Costa Rica 2020 tour was a photographic trip focusing on the birds and wildlife that this fascinating country has to offer. Without the rush to build a large list of species but rather with the intention to get a large amount of good photos while enjoying bird sightings and behavior we had a fantastic time on our trip. We started our trip in Alajuela near San José’s Juan Santamaría International Airport and from there drove across the country, visiting different areas including the Caribbean lowlands in the north with obligatory stops at La Selva Biological Station, Sarapiquí, the Cinchona feeders, and the private Donde Cope nature center. Our time here was fantastic; we had the opportunity to see and photograph birds such as the endemic Coppery-headed Emerald, Black-bellied Hummingbird, Semiplumbeous Hawk, Great Green Macaw, White-tipped Sicklebill, Great Potoo, Spectacled Owl, Violet Sabrewing, Red-headed Barbet, Prong-billed Barbet, Blue-throated Toucanet, Yellow-throated Toucan, Keel-billed Toucan, White- necked Puffbird, Buff-fronted Quail-Dove, Black Guan, Buff-rumped Warbler, and the fabulous Snowcap. Our trip continued to the cloudforest mountains at San Gerardo de Dota at the famous Savegre Hotel, where we managed to record species such as Large-footed Finch, Yellow-thighed Finch, Spotted Wood Quail, Wrenthrush, Hairy Woodpecker, Long-tailed Silky-flycatcher, Black- and-yellow Phainoptila, Golden-browed Chlorophonia, Acorn Woodpecker, Slaty Flowerpiercer, Fiery-throated Hummingbird, Talamanca Hummingbird, Volcano Junco, Timberline Wren, and the most-wanted Resplendent Quetzal. -
