6.5 Coastal Cactus Wren (Campylorhynchus Brunneicapillus Sandiegensis) – Category SO Management Units with Known Occurrences
Volume 2D: Goals and Objectives for Species Focus Management Species 6.0 Birds 6.5 Coastal Cactus Wren (Campylorhynchus brunneicapillus sandiegensis) – Category SO Management Units with Known Occurrences Coastal cactus wrens are restricted to cactus-dominated coastal sage scrub habitats in Southern California, from Ventura south to San Diego County and inland to western San Bernardino and western Riverside Counties. These wrens differ ecologically from more common desert wrens in the southwestern United States and northern Mexico. Coastal cactus wrens began significantly declining in San Diego County in the early 1980s due to habitat loss to agriculture and urban development (Rea and Weaver 1990). By 1990 there was a 33% population decline from the previous decade as a result of the loss of coastal birds and smaller populations, and a decline in abundance of remaining populations. Coastal cactus wren surveys and cactus mapping were implemented on Conserved Lands in the MSPA in 2009 and 2011 (USFWS 2011). Cactus wrens were documented on Conserved Lands in MUs 1, 2, 3, 4, 5, and 6 (see Occurrence Table and online map: http://arcg.is/2kU1bka). A range-wide genetics and banding study was conducted across occupied cactus scrub habitats in 2011–2013 by USGS to determine coastal cactus wren population genetic structure, connectivity, and genetic diversity in Southern California (Barr et al. 2015). The study found 3 main genetic clusters in San Diego County: Otay; San Diego/El Cajon (Sweetwater/Encanto/Lake Jennings); and San Pasqual. In the San Diego/El Cajon genetic cluster, wrens in the Sweetwater River watershed are connected to occurrences in Fletcher Hills and Lake Jennings to the northeast in MU4 and to occurrences in Encanto Canyon and other urban canyons to the west in MU2. -

Nest-site characteristics of Rufous-naped Wrens Artículo (Campylorhynchus rufinucha) in Acacia trees may serve to avoid vertebrate predators Características de sitios de los nidos de Campylorhynchus rufinucha en árboles de Acacia posiblemente sirven para evadir depredación por vertebrados Ignacio Escalante1 1Sistema de Estudios de Posgrado, Escuela de Biología, Universidad de Costa Rica. San José, Costa Rica. Ornitología Colombiana Ornitología [email protected] Abstract The high rate of nest predation in tropical birds results in strong selection pressure. The Rufous-naped Wren (Campylorhynchus rufinucha) nests in Bullhorn trees (Acacia) in the Mesoamerican dry forest. It has been proposed that bullhorns and their aggressive ants (Pseudomyrmex spp.) help to prevent nest predation. I tested the hypothesis that these birds place their nests in particular acacia micro- habitats to avoid predation by vertebrates such as tufted capuchin monkeys (Cebus capucinus). I expected to find nests in locations that avoided the foraging behavior preferences of the monkeys. Along 6 km gravel road in Palo Verde National Park, Guanacaste, Costa Rica, I found 52 Rufous-naped Wren nests. The proportion of ant species in acacias with nests did not differ from the background proportion of ant species in acacias without nests, so birds did not prefer to nest in acacias with the most aggressive ant species. Acacia trees with wren nests were larger in diameter than control acacias without nests. I found more nests in acacias that were clustered, which consisted of one to five acacias in a 3m radius plot around the acacia with nest. However, the number of acacias with or without nests did not differ in their isolation from other non-acacia trees. -

E-mail: [email protected] Abstract We investigated if passerine birds act as important predators of small vertebrates within the Neotropics. We surveyed published studies on bird diets, and information on labels of museum specimens, compiling data on the contents of 5,221 stomachs. Eighteen samples (0.3%) presented evidence of predation on vertebrates. Our bibliographic survey also provided records of 203 passerine species preying upon vertebrates, mainly frogs and lizards. Our data suggest that vertebrate predation by passerines is relatively uncommon in the Neotropics and not characteristic of any family. On the other hand, although rare, the ability to prey on vertebrates seems to be widely distributed among Neotropical passerines, which may respond opportunistically to the stimulus of a potential food item. -

Life History Account for Gila Woodpecker
California Wildlife Habitat Relationships System California Department of Fish and Wildlife California Interagency Wildlife Task Group GILA WOODPECKER Melanerpes uropygialis Family: PICIDAE Order: PICIFORMES Class: AVES B297 Written by: M. Green Reviewed by: L. Mewaldt Edited by: R. Duke,D. Winkler DISTRIBUTION, ABUNDANCE, AND SEASONALITY An uncommon to fairly common resident in southern California along the Colorado River, and locally near Brawley, Imperial Co. Occurs mostly in desert riparian and desert wash habitats, but also found in orchard-vineyard and urban habitats, particularly in shade trees and date palm groves. Formerly found in farm and ranchyards throughout the Imperial Valley, but most regularly now near Brawley. Numbers have declined greatly in southern California in recent decades (Remsen 1978, Garrett and Dunn 1981). SPECIFIC HABITAT REQUIREMENTS Feeding: Eats insects, mistletoe berries, cactus fruits, corn (Gilman 1915, Ehrlich et al. 1988), and occasionally contents of galls on cottonwood leaves, bird eggs, acorns, cactus pulp (Speich and Radke 1975). Gleans from trunks and branches of trees and shrubs. Cover: Cottonwoods and other desert riparian trees, shade trees, and date palms supply cover in California. Saguaros are important habitat elements outside of California, but are scarce within the state and are not so important. Reproduction: Nests in cavity in riparian tree or saguaro. Water: No data found. Characteristically forages and nests in riparian areas in California. Pattern: Groves of riparian trees, planted shade trees, and date palm orchards provide cover. SPECIES LIFE HISTORY Activity Patterns: Yearlong, diurnal activity. Seasonal Movements/Migration: Resident within California. May wander in nonbreeding seasons. There are 2 old records in southern, coastal California. -
Bird List of San Bernardino Ranch in Agua Prieta, Sonora, Mexico
Bird List of San Bernardino Ranch in Agua Prieta, Sonora, Mexico Melinda Cárdenas-García and Mónica C. Olguín-Villa Universidad de Sonora, Hermosillo, Sonora, Mexico Abstract—Interest and investigation of birds has been increasing over the last decades due to the loss of their habitats, and declination and fragmentation of their populations. San Bernardino Ranch is located in the desert grassland region of northeastern Sonora, México. Over the last decade, restoration efforts have tried to address the effects of long deteriorating economic activities, like agriculture and livestock, that used to take place there. The generation of annual lists of the wildlife (flora and fauna) will be important information as we monitor the progress of restoration of this area. As part of our professional training, during the summer and winter (2011-2012) a taxonomic list of bird species of the ranch was made. During this season, a total of 85 species and 65 genera, distributed over 30 families were found. We found that five species are on a risk category in NOM-059-ECOL-2010 and 76 species are included in the Red List of the International Union for Conservation of Nature (IUCN). It will be important to continue this type of study in places that are at- tempting restoration and conservation techniques. We have observed a huge change, because of restoration activities, in the lands in the San Bernardino Ranch. Introduction migratory (Villaseñor-Gómez et al., 2010). Twenty-eight of those species are considered at risk on a global scale, and are included in Birds represent one of the most remarkable elements of our en- the Red List of the International Union for Conservation of Nature vironment, because they’re easy to observe and it’s possible to find (IUCN). -

The Social System of Sharpe's Wren (Cinnycerthia Olivascens)
The social system of Sharpe’s Wren (Cinnycerthia olivascens): Artículo fluid group composition in a cooperative breeder El sistema social del cucarachero de Sharpe: fluidez en la composición de grupos en un ave con cría cooperativa. Gustavo H. Kattan1,2 Mónica Parada2 & J. William Beltrán2,3 1 Departamento de Ciencias Naturales y Matemáticas, Pontificia Universidad Javeriana Cali, Calle 18 No. 118-250, Cali, Colombia. 2 Ornitología Colombiana Ornitología Fundación EcoAndina, Carrera 2 A Oeste No. 12-111, Cali, Colombia. 3 Department of Biology, University of Puerto Rico, San Juan PR 00931 [email protected] Abstract Cooperatively breeding birds live in groups that normally originate in the retention of offspring, which delay dispersal and stay in the parental territory, helping to raise close kin. Group transfers usually occur when individuals disperse to obtain re- productive positions. Between 1995 and 2000 we studied the social system of Sharpe's Wren (Cinnycerthia olivascens) in an Andean forest. Wrens lived all the time in groups of up to seven individuals that maintained year-round, all-purpose territo- ries (mean = 7.6 ha) and raised offspring cooperatively. Each group had only one breeding pair, and produced 1-3 fledglings. Group composition was highly variable. Birds of all age classes frequently joined and abandoned groups. Birds became helpers when joining new groups. In one case a female breeding vacancy was filled by a bird that had joined the group two and a half years earlier. Four focal groups each had up to 20 different, temporary members in three years of ob- servation, and only the breeding pair was permanent.
