(Junonia coenia on Helianthus annuus) important ecological but threatened riparian landscapes (Provencher et al. 2005). Not only does the Warm Springs Natural Area encompass the majority of Muddy River tributaries it is also the largest single tract of land in the upper Muddy River set aside for the benefit of native species in perpetuity. The prominence of water in an otherwise barren Mojave landscape provides an oasis for regional wildlife. A high bird diversity is attributed to an abundance of riparian and floodplain trees and shrubs. Contributions to plant diversity come from the Mojave Old World swallowtail (Papilio machaon) Desertsnow (Linanthus demissus) Lobe-leaved Phacelia (Phacelia crenulata) Cryptantha (Cryptantha sp.) vegetation that occur on the toe slopes of the Arrow Canyon Range from the west and the plant species occupying the floodplain where they are supported by a high water table. Several marshes and wet meadows add to the diversity of plants and animals. The thermal springs and tributaries host an abundance of aquatic species, many of which are endemic. The WSNA provides a haven for the abundant wildlife that resides permanently or seasonally and provides a significant level of protection for imperiled species.

Nesters inhabit cottonwood, willow, mesquite, and other vegetation in desert riparian habitat adjacent to irrigated fields, irrigation ditches, pastures and other open, mesic areas in isolated patches throughout central southern California. Numbers have declined drastically in the Imperial and Coachella valleys and along the Colorado River, primarily because of loss of habitat (Grinnell and Miller 1944, Gaines 1977c, Remsen 1978, Garrett and Dunn 1981). Despite local extirpations in the Coachella and Imperial valleys, the overall breeding range has expanded in recent years to the north and west (Myers 2008). SPECIFIC HABITAT REQUIREMENTS Feeding: Sallies for flying insects, especially bees, from exposed perches on outer portions of low trees, shrubs, and tall herb stalks, or picks insects from ground. Frequently feeds just above water surface. Regurgitates pellets (Bent 1942). Cover: Trees and large shrubs afford nesting and roosting sites, and other cover. Reproduction: Nest a compact, open cup of twigs, fine grasses, rootlets, bound with spider silk. Built in the fork of a horizontal branch in willow, cottonwood, mesquite, or other large tree or shrub. Nest height generally 2.5 to 6.2 m (8-20 ft), rarely to 15.5 m (50 ft) above ground (Bent 1942, Tinkham 1949).

The Black Oystercatcher Haematopus bachmani , a monotypic species, is one of the less studied members of the genus. The global population of roughly 10,000 individuals is scattered unevenly along the North American Pacific Ocean coast from the Aleutian Islands to Baja California, with the vast majority (about 80%) in Alaska and British Columbia. Favouring rocky shorelines in areas of high tidal variation, they forage exclusively on intertidal macroinvertebrates (e.g. limpets and mussels). Because they are completely dependent on marine shorelines, the Black Oystercatcher is considered a sensitive indicator of the health of the rocky intertidal community. Breeding oystercatchers are highly territorial, and nesting densities are generally low; however, during the winter months they tend to aggregate in groups of tens to hundreds.

    ECCENTRIC FIRST-YEAR MOLT PATrERNS IN CERTAIN TYRANNID FLYCATCHE!.S PETER PYLE, Point ReyesBird Observatory,4990 ShorelineHwy., StinsonBeach, California 94970 Most passerinesfollow a similarsequence of remex molt, replacementof the primariescommencing with the innermostand proceedingdistally, while that of the secondaries(except for the tertials, S7-S9) beginswith the outermostand proceeds proximally (Ginn and Melville 1983). Duringthe first- year molts(here defined as all periodsof moltingbefore the secondprebasic molt),many passerines replace no remigeswhereas others replace some or all remiges(Pyle et al. 1987, Jenni and Winkler 1994). "Incomplete"first-year remexmolts occasionally result when the typicalmolting sequence is arrested, the distaljuvenal primaries and proximalsecondaries (excluding the tertials) being retained.This pattern of incompletemolt is found in severalNorth Americanpasserines, notably, the Phainopepla(Phainopepla nitens), North- ern Cardinal (Cardinalis cardinalis), and Lark Sparrow (Chondestes grammacus)(Pyle et al. 1987, Thompsonand Leu 1994). In a few passerinespecies, incomplete first-year primary molts (and in some casessecondary molts) that do not follow the typical sequencebut involvereplacement of centralor distalprimaries in varyingpatterns have been documented(Jenni and Winkler 1994, Thompson and Leu 1994). These replacementpatterns, termed "eccentric"by Jenni and Winkler (1994), are poorly understood.A common eccentricreplacement pattern involvesrenewal of the outer four to six primariesand inner three to five secondaries,feather replacementproceeding distally in the primariesand proximallyin the secondaries,as in the typicalsequence, but commencingat differentpoints along the wing (Jenni and Winkler 1994; Figure 1). This pattern has been documentedin severalNorth American passerines,nota- bly, the LoggerheadShrike (Lanius ludovicianus),Yellow-breasted Chat (Icteria virens),and Passerina buntings (Miller 1928, Phillips1974, Thomp- son and Leu 1994).

    Birding and Natural History in Southeast Arizona May 12

    Birding and Natural History in Southeast Arizona Mark Pretti Nature Tours, L.L.C. and the Golden Gate Audubon Society May 12 - 18, 2022 Southeast Arizona is one of the most biologically diverse areas in the United States. Habitats include the Sonoran Desert with its dramatic columnar cacti, the Chihuahuan desert with its grasslands and desert scrub, and the dramatic “Sky Islands” where species from the Rocky Mountains and Mexico’s Sierra Madre come together. During our journey, we’ll explore most of these habitats, encounter a great diversity of plants and animals, and enjoy fine weather at one of the richest times of year. We’ll visit many of the birding and wildlife hotspots – Madera Canyon, the Patagonia area, Huachuca Canyon, and the San Pedro River. Species we’re likely to see include elegant trogon, gray hawk, zone-tailed hawk, vermilion flycatcher, painted redstart, Grace’s, Lucy’s, red- faced and other warblers, three species of Myiarchus flycatcher (ash-throated, brown- crested, and dusky-capped), thick-billed kingbird, northern beardless tyrannulet, greater pewee, yellow-eyed junco, up to seven species of hummingbirds, many sparrows (five- striped, Botteri’s, rufous-winged, black-throated, rufous-crowned), Scott’s oriole, and many others. In addition to birds, the area is well known for its butterfly diversity, with the Huachuca Mountains alone harboring almost one-quarter of all the butterflies found in the U.S. While May is not the peak season for butterflies, we should see as many as 15 - 20 species. Mammal diversity in the area is also high, and we've seen 20 species on past trips - these include round-tailed ground-squirrel, Arizona gray squirrel, Coues' white-tailed deer, pronghorn, black-tailed jackrabbit, coyote, bobcat, coatimundi, and javelina.

However, both speciation and hybridization can occur with neg- ligible morphological differentiation. The Northwestern Crow (Corvus caurinus) and American Crow (Corvus brachyrhynchos) are sister taxonomic species with a continu- ous distribution that lack reliable traditional characters for identification. In this first population genomic study of Northwestern and American crows, we use genomic SNPs (nuDNA) and mtDNA to investigate whether these crows are genetically differentiated and the extent to which they may hybridize. We found that American and North- western crows have distinct evolutionary histories, supported by two nuDNA ancestry clusters and two 1.1%-divergent mtDNA clades dating to the late Pleistocene, when glacial advances may have isolated crow populations in separate refugia.

The most extreme variations of abnormal pigmentation occur in individuals that show marked reductions A xanthochroistic (flavistic) male Vermilion Flycatcher or increases in the normal pigments present (HARRISON 1985). Pyrocephalus rubinus (Fig 2) was photographed in Dry Chaco Though probably not uncommon in nature (HOSNER scrub at Fortín Toledo, Departamento Boquerón on 12 October & LEBBIN 2006, VAN GROUW 2013), individuals exhibiting 2013. The red areas of the typical plumage had been completely plumage aberrations frequently find themselves at a selective replaced by pale orange-yellow. Xanthochroism is a genetic or disadvantage and thus may be short-lived, meaning that they dietary induced condition affecting the carotenoid pigments for are rarely observed. Some aberrant individuals are more red coloration, replacing them with yellow (GÓMEZ et al.
