Occurrence of Snowy and Collared Plovers in the Interior of Mexico OCCURRENCE OF SNOWY AND COLLARED PLOVERS IN THE INTERIOR OF MEXICO STEVE N. G. HOWELL and SOPHIE WEBB, Point ReyesBird Observatory,4990 ShorelineHighway, Stinson Beach, California 94970 The A.O.U. (1983) noted breedingby Snowy Plovers(Charadrius alexandrinus) in the interior of North America south to southernArizona and southernNew Mexico;all recordsfor Mexico (breedingand winter) were coastal.The Collared Plover (Charadrius collaris) is describedas residentfrom Sinaloaand Veracruzsouth through Middle America, prima- rily in coastalareas (A.O.U. 1983, Friedmannet al. 1950). We detailhere severalrecent records(since 1982) of both of these ploversfrom the interior of northern and central Mexico. Our hope is to make observers awareof the potentialoccurrence of Snowyand Collared plovers at sitesin the interiorof Mexico.Figure I showssites mentioned for SnowyPlovers in the followingaccounts. SNOWY PLOVER Coahuila At Presa El Tulillo (25ø40' N, 101ø24 ' W; elevation 1100 m), a reservoir 50 km west-northwestof Saltillo,we noted four to five basic-plumaged SnowyPlovers along the southshore on 27 November1986. Aldegundo Garzade Leon (pers.comm.), an ornithologistresident in Saltillo,collected two SnowyPlovers (numbers 778 and 779 in hiscollection) at El Tulilloon 21 March 1982, but has found no evidencethat the speciesnests at this site. Zacatecas At PresaAcecatecana (22ø44 ' N, 102ø33' W; 2150 m), a largereservoir southof the bypasson the southside of the city of Zacatecas,we found 11 or 12 alternate-plumagedSnowy Plovers on 27 June 1991 in an extensive dry muddyarea alongthe reservoir'snortheast corner, near the dam. The birds includedthree or four apparent pairs, which gave the upslurred chuweepand low perrt callstypical of nestingbirds. We saw one bird apparentlytrying to leadanother into a smallarea where the firstbird would sit down as if in a nest scrape;however, we found no eggs.Howell visited this reservoiron 4 January1984 and 12 April 1987 but saw no Snowy Plovers on those dates. To our knowledge,the only previousreport from Zacatecasis of three seen,and an adultfemale collected,at a shallowlake 8 km eastof Noria de losAngeles in the southeastof the state,3 August1959 (Webster1968); this site is 25 km due south of Salinasde Hidalgo, San Luis Potosi (see following). 146 WesternBirds 25:146-150, 1994 SNOWY AND COLLARED PLOVERS IN MEXICO San Luis Potosi On 28 June 1991, immediatelywest of the town of Salinasde Hidalgo, in western San Luis Potosi (22038 ' N, 101045 ' W; 2100 m), we saw six to eightpairs of SnowyPlovers, including an adultwith two smallchicks, at the largestlagoon south of Highway49. We have foundno previousrecords from San Luis Potosi. Ouanajuato At the smallreservoir southwest of Highway 111, 5 km eastof Dolores Hidalgo(21008 ' N, 100053' W; 1900 m), P. Pyle and Howell saw a single basic-plumagedSnowy Plover on 6 January1984. We havefound no other recordsof the speciesfrom Guanajuato.

At the muchlarger shallow seasonal lake east of highway54D betweenkilometer posts35 and40, Howellnoted at least100 SnowyPlovers on 27 February 1993; none showedany indicationsof nesting.We knowof no previous records from Jalisco. Puebla LagunaTotolcingo, a vastshallow lake, straddles the easternborder of Tlaxcala with the state of Puebla (19ø20' N, 97ø62 ' W; 2200 m). On 12 December1986 we saw 100+ SnowyPlovers on the extensivesalt fiats borderingthe lake north of Highway136, all apparentlyin the stateof Puebla.At least 40% of the birdswere in full alternateplumage, 20% or more were in basicplumage, and 30% of the birdswere juveniles, some in veryfresh plumage; the remainderwere too distantfor theirplumage to be assessedaccurately. We havefound no otherrecords from Puebla. Howell visitedthis lake on 21 January1984 but sawno SnowyPlovers. The large expanseof the lakeand salt flats, however, combined with fluctuating water levels,means that at any giventime muchof the area may be generally inaccessibleto observersand/or unsuitablefor plovers. M•xico/Distrito Federal The onlyrecords of the SnowyPlover from the DistritoFederal are of singlealternate-plurnaged birds seen at the relativelyheavily birded marshes on the southside of MexicoCity (19ø16' N, 99ø08' W; 2200 m), at San GregorioAtlapulco on 22 April 1985 (Wilsonand Ceballos-L. 1986), and at Tlahuacon 22 April 1992 (Howelland R. G. Wilson).Snowy Plovers occurin summerand maynest at LagoTexcoco (19ø30 ' N, 99ø02'W) on the Mexico/D.E border(wilson and Ceballos-L.1986, R. G. Wilsonpers. comm.). COLLARED PLOVER CollaredPlovers are residentlocally along rivers in the lowlandson both coastalslopes of Mexico,and we haveseen them up to 250 km from the coast(e.g., at Yaxchilan,Chiapas). Such records,however, are all in the tropicallowlands (below 500 m elevation).Records that fall outsidethis patternare listedbelow. Jalisco At the extensivemarshes and lakesbeside Highway 54D northof Sayula (20o02' N, 103o34' W; 1500 m), we saw five CollaredPlovers, including two apparentpairs, on 31 March1988, andHowell noted four birds on 10 March 1989 and four on 27 February1993. 148 SNOWY AND COLLARED PLOVERS IN MEXICO Tlaxcala On 21 January1984, P. Pyle and Howell founda CollaredPlover at a small pool in the short-grassplains bordering Laguna Totolcingo,in Tlaxcala.They realizedthe rarityof suchan occurrenceand carefullynoted the bird'selegant, slender build and slender,all-black bill. Other features notedwere the bold,clean-cut white foreheadpatch, the complete,narrow black chest band, a rufouswash to the sidesof the head, lack of a white hindcollar,and the slender,pale flesh-colored legs. This is the onlyrecord of CollaredPlover we are aware of from the Mexicanplateau. Morelos At LagunaE1 Rodeo (18046 ' N, 99020' W; 1000 m), a smallnatural lake 15 km south-southwestof Cuernavaca,R. G. Wilson (pers. comm.) re- cordedup to four CollaredPlovers in the wintersof 1983/1984 (alsoseen by Howell and P. Pyle), 1986/1987, and 1989/1990, with extremedates of 8 Octoberand 15 March. We saw none at El Rodeo on 20 May 1990, and R. G. Wilson (pers.comm.) has seen none there duringseveral visits from April to September. Guerrero At Lagunade Tuxpan(18022 ' N, 99030' W; 750 m), a large lake 2 km eastof Iguala,we and R. G. Wilsonsaw three to five CollaredPlovers along the southshore on 16 December 1986. We saw none there on 20 May 1990 or 2 June 1986. DISCUSSION Theseobservations indicate that SnowyPlovers breed locally in summer at lakesand reservoirson the Mexicanplateau. While our onlycertain proof of nestingwas the chicksin San LuisPotosi, the callsand behaviorof the birdsin Jaliscoand Zacatecasstrongly suggest that they alsowere nesting. The speciesalso may nest at LagoTexcoco, state of M•xico. By December, many winteringSnowy Plovershave attainedalternate plumage(G. W. Page pers. comm.), which may explain our observation at Laguna Totolcingo.The numberof fresh-plumagedjuveniles there, however,may alsosuggest late summernesting by SnowyPlovers at or near the site. NonbreedingSnowy Plovers, possibly from the interiorof NorthAmerica, occur as winter migrantsto the Mexican plateau, with specificrecords between November and March. The two April records, both from the DistritoFederal, may representmigrants headed for nestingsites in Mexico, sincemost Snowy Plovers nesting in the interiorand on the Pacificcoast of the U.S. have by then arrivedat breedingareas (G. W. Page pers. comm.). Clearly, more field work is needed to determinethe nestingseason, distribution,and breedingand winter abundanceof Snowy Ploversin the interior of Mexico; for example, numerouslarge shallowlakes on the Mexicanplateau in the statesof Chihuahuaand Durangohave never been surveyedfor Snowy Plovers.The dearth of recordsfor both Snowy and Collaredplovers from the interiorof Mexico prior to the 1980s probably 149 SNOWY AND COLLARED PLOVERS IN MEXICO reflectsa lack of observercoverage rather than range expansionby either species. The CollaredPlover appears to be a winter visitor(October to March)to lakesin the Rio Balsasdrainage of interiorsouthwest Mexico and a winter vagrantto the centralhighlands (the January record from Tlaxcala). There is no evidenceof breedingby CollaredPlovers at the lakesin Guerreroand Morelos. Although Widrig (1983) reported Collared Plovers nesting in Decemberin coastalNayarit, other known nestingdates from southwest coastaland interior Mexico are in spring: on 11 April 1988 at Puente Mexcalhuacan,Michoacan, we found

    24 Aquatic Birds at the Taiamã Ecological Station: Seasonal Variation of Community Structure and the Importance of Protected Areas in the Pantanal Daniel Luis Zanella Kantek1, Roselaine Carvalho de Melo2, Selma Samiko Miyazaki1, Welvis Felipe Fernandes Castilheiro2 & Manoel dos Santos Filho2 Recebido em 30/03/2020 – Aceito em 20/06/2020 1 Instituto Chico Mendes de Conservação da Biodiversidade, Estação Ecológica deTaiamã, Cáceres/MT, Brasil. <[email protected], [email protected]>. 2 Departamento de Ciências Biológicas, Programa de Pós-Graduação em Ciências Ambientais, Universidade do Estado de Mato Grosso, Cáceres/MT, Brasil. <[email protected], [email protected], [email protected]>. ABSTRACT – As the largest floodplain in the world, the Pantanal plays an important role in maintaining biological diversity. Taiamã Ecological Station (TES) is a protected area located in the north Pantanal; it is considered a relevant area for bird conservation. The species composition of these areas must be studied and known for the development of specific management plans. Besides, waterfowl are important in assessing quality and are highly sensitive to environmental changes. Thus, we investigated the aquatic bird composition at the TES and surrounding area and evaluated the richness and abundance levels among sites and the river level during one year of sampling. We performed a total sample effort of six campaigns, with four sites sampled: two at the TES and two in the surroundings. We identified a total of 45 aquatic bird species, divided into nine orders, 20 families and 36 genera. The large number of individuals observed in February 2012 can be related to a natural phenomenon that occurs in Pantanal, called ‘dequada’, which is associated with the processes of decomposition of submerged plant biomass at the beginning of the flood.

  • Practical Guide for Breeding Ecology of Kentish Plover
    Practical guide for investigating breeding ecology of Kentish plover Charadrius alexandrinus Tamás Székely, András Kosztolányi & Clemens Küpper Department of Biology & Biochemistry, University of Bath, Bath BA2 7AY, UK [email protected] [email protected] [email protected] Version 3, 1 April 2008 Photos by T. Székely, A. Kosztolányi & C. Küpper Rationale The Kentish/snowy plover Charadrius alexandrinus is a small cosmopolitan shorebird (body mass about 40-44 g). In the last few years we have developed a suite of methods to investigate its behaviour and ecology in the field. We thought this practical guide may be useful for students and researchers with an interest in small plovers. Some aspects of these methods may be relevant for other shorebirds and ground-nesting birds in general. Our fundamental motivation in writing this guide is to show that the Kentish plover is an easy species to work with, if one is willing to pay attention to a few potential pitfalls. We hope that this guide will elicit further research. Please contact us if you have questions and comments, and let us know of any errors. Note that Kentish plovers have been studied in several countries and by a good range of researchers, and we don't claim that our methods work best. Many Kentish plover populations are now declining. You need to be sensible about fieldwork, and carefully evaluate the costs and benefits of using a particular method. The last thing you want is to put an extra burden on plover populations - they have a hard time anyway to cope with predators, floods and threats humans are imposing upon them.

  • Empidonax Traillii) in Ecuador and Northern Mexico
    Winter Distribution of the Willow Flycatcher (Empidonax traillii) in Ecuador and Northern Mexico Submitted to: U.S. Bureau of Reclamation Boulder City, AZ Prepared by: Catherine Nishida and Mary J. Whitfield Southern Sierra Research Station P.O. Box 1316 Weldon, CA, 93283 (760) 378-2402 March 2006 EXECUTIVE SUMMARY Concern for the southwestern willow flycatcher (Empidonax traillii extimus) has stimulated increased research, management, and conservation of the species on its North American breeding grounds. To supplement current knowledge of breeding populations, recent studies in Latin America (Koronkiewicz et al. 1998; Koronkiewicz and Whitfield 1999; Koronkiewicz and Sogge 2000; Lynn and Whitfield 2000, 2002; Nishida and Whitfield 2003, 2004) have focused on wintering ecology. We extended these efforts by surveying for willow flycatchers from 8–24 December, 2004 in northern Mexico and 18–28 January, 2005 in Ecuador. Our goals were to identify territories occupied by wintering willow flycatchers, describe habitat in occupied areas, collect blood and feather samples, collect colorimeter readings, relocate banded individuals, and identify threats to willow flycatcher populations on the wintering grounds. We spent a total of 103.7 survey hours at 30 survey sites in northern Mexico and Ecuador. In northern Mexico, we surveyed four new locations and revisited three locations from our initial 2002 surveys of Mexico. We detected a minimum of 52 willow flycatchers (Sinaloa = 2, Nayarit = 50). In Mexico, occupied habitat was found along the Pacific coast lowlands. In Ecuador, we revisited locations that had been surveyed annually since 2003 (except Sani, which was surveyed 2004–2005) and found high willow flycatcher densities at a new location along the Río Coca.

  • Periodic Status Review for the Snowy Plover in Washington
    STATE OF WASHINGTON February 2016 Periodic Status Review for the Snowy Plover Derek W. Stinson Washington Department of FISH AND WILDLIFE Wildlife Program The Washington Department of Fish and Wildlife maintains a list of endangered, threatened, and sensitive species (Washington Administrative Codes 232-12-014 and 232-12-011). In 1990, the Washington Wildlife Commission adopted listing procedures developed by a group of citizens, interest groups, and state and federal agencies (Washington Administrative Code 232-12-297). The procedures include how species list- ings will be initiated, criteria for listing and delisting, a requirement for public review, the development of recovery or management plans, and the periodic review of listed species. The Washington Department of Fish and Wildlife is directed to conduct reviews of each endangered, threat- ened, or sensitive wildlife species at least every five years after the date of its listing by the Washington Fish and Wildlife Commission. The periodic status reviews are designed to include an update of the species status report to determine whether the status of the species warrants its current listing status or deserves reclas- sification. The agency notifies the general public and specific parties who have expressed their interest to the Department of the periodic status review at least one year prior to the five-year period so that they may submit new scientific data to be included in the review. The agency notifies the public of its recommenda- tion at least 30 days prior to presenting the findings to the Fish and Wildlife Commission. In addition, if the agency determines that new information suggests that the classification of a species should be changed from its present state, the agency prepares documents to determine the environmental consequences of adopting the recommendations pursuant to requirements of the State Environmental Policy Act.

  • Plover, Snowy
    Plovers — Family Charadriidae 193 Snowy Plover Charadrius alexandrinus Nesting on beaches, dunes, and salt flats, the Snowy Plover is among San Diego County’s scarcest and most threatened breeding birds. In 1993 the U.S. Fish and Wildlife Service listed it as threatened along the entire Pacific coast. Thorough surveys from 1995 to 1998 put the county’s breeding population between 240 and 325 individuals, most concentrated in two areas, Camp Pendleton and the Silver Strand (Powell et al. 2002). Surveys from 1978 to 1998 suggest the decline of this once common bird has continued.

  • 6.2 Western Snowy Plover (Charadrius Nivosus Nivosus) – Category SL
    Volume 2D: Goals and Objectives for Species Focus Management Species 6.0 Birds 6.2 Western Snowy Plover (Charadrius nivosus nivosus) – Category SL Management Units with Known Occurrences The Pacific coast population of the western snowy plover is a federally threatened and State-Species of Special Concern that breeds primarily from southern Washington to southern Baja California, Mexico, and in interior areas of Oregon, California, Nevada, and several other western states (USFWS 2007). Genetically isolated from western snowy plovers found in the interior of North America (USFWS 1993), the Pacific coast population requires breeding grounds above the high-tide line on coastal beaches, beaches at creek and river mouths, and salt pans at lagoons and estuaries. These plovers may also take advantage of bluff-backed beaches, dredged material disposal sites, salt pond levees, dry salt ponds, and river bars (USFWS 2007). Monitoring of this species is intensive and has been ongoing since 1977 by the Point Reyes Bird Observatory. In San Diego county, monitoring of populations on military installations started in 1999, while USGS intensely monitored these plovers in San Diego County from 1994 through 1998 (Powell et al. 2002; USFWS 2007). Unitt (2004) reports that populations are found largely in MCB Camp Pendleton at the Santa Margarita River mouth, Batiquitos Lagoon, and Silver Strand State Beach, with occurrences mostly observed in MUs 1, 6, and 7. The results of the 1994 through 1998 USGS surveys indicated the continual high risk of decline and possible local extinction of the Pacific coast population (Powell et al. 2002).
