HUITZIL (2006) 7: 15-17  The Sparkling-tailed Hummingbird (Tilmatura dupontii Lesson 1832) or colibrí cola pinta (Escalante et al. 1996) is a Mesoamerican endemic considered threatened by the Mexican government (SEMARNAT 2002).  Tilmatura dupontii feeds on nectar and insects (Wagner 1946, Howell and Web 1995).  It inhabits different types of highland habitats, like open woods and shrub zones, humid and semiarid forests edges and brushy second growth and scrubby woodlands often with oaks (Peterson and Chalif 1989, Howell and Webb 1995, Schuchmann 1999).  Altough it has been considered a local resident fairly common to uncommon, between 500 and 2500 m asl, along its geographical distribution range, its abundance can vary greatly among years and seasonally (Howell and Webb 1995; Schuchmann 1999) and particularly in México, based on the evidence presented by several authors, seems that the species is rare and hard to detect (Edwards and Lea 1955, Arizmendi 2001, Ortiz-Pulido and Díaz 2001, Peterson et al. 2004).  Ornelas (1987) reported T. dupontii for an evergreen subtropical forest at Guerrero (1350 m asl) for the months of January, April and May.  During one year of monthly sampling at Sierra de Manantlán Biosphere Reserve, Arizmendi (2001) registered only five individuals of this species, all in disturbed areas of humid pine forest and pine forest – cloud forest transition (above 1900 m asl) during February and June.  Ortíz-Pulido and Díaz (2001) reconfirm its presence in the lower central portion of Veracruz, after 50 years of any record for the species on this area.  The observation was done in a site covered by agricultural lands and acahuales.  Recently Forcey (2002a, 2002b) registered the species for the first time for central Oaxaca.  He considered this species as a short distance vagrant or rare transient migrant from lowland areas.  One of the few studies in México, where T. dupontii was noticed to be quite abundant is that of Davis HUITZIL Vol. 7, No. 1 (2006)                     www.huitzil.net 15                   _Nuevos registros-_      Figure 1. Photograph of a male individual of Sparkling-tailed Woodstar (Tilmatura dupontii; Trochilidae) registered for the first time for the Sierra de Huautla Biosphere Reserve, Morelos, México (the photograph was taken with an Olympus© Digital Camera C-765 Ultra Zoom, with flash and in auto mode).  (1953) for the Tzitzio region, Michoacán, where he recorded 21 individuals in July and August on areas of oak-thorn scrub and heavy riparian vegetation.   Its occurrence has been associated with blooming events and high abundance of flowers (Gómez de Silva et al. 1999, Forcey 2002b).  Its have been reported to feed from flowers of the plants Sechium compositum (Cucurbitaceae), Hamelia patens (Rubiaceae), Fuchsia microphylla (Onagraceae), Salvia mexicana and S. iodantha (Lamiaceae; Gómez de Silva et al. 1999, Arizmendi 2001, Lasso and Naranjo 2003).   Its presence in the Mexican state of Morelos it is considered rare (Urbina 2005) and it was reported for the first time in the 1950’s (Friedmann et al. 1950, Blake 1953) with one individual collected in July in Cuernavaca city (no further information of the site is provided; Davis and Russell 1953), then in May of 1988 in the municipality of Tlayacapan (Urbina 2005), in an area dominated by agricultural land and patches of oak forest and tropical dry forest. Both sites are over 1600 m asl.  Its presence in Morelos is reported in the American Ornithologists' Union checklist of North American birds (AOU 1998).   One male individual of Sparkling-tailed Hummingbird was detected on August 16, 2005, while conducting observations on the rate of pollinator visitors to plants of the Firerbush shrub (H. patens) a known hummingbird pollinated plant (Lasso and Naranjo 2003) and one of the most conspicuous shrub in the study site.  At 7:09 hrs a characteristic low, insect – like humming sound was heard and one individual of this species was noticed visiting flowers to feed and then flew away of sight, one minute later it came back into sight, feed on 13 other flowers and then it perched on a branch inside the shrub.  It could be observed using binoculars and its long and bifurcated tale with clear patches was noticed before it flew away to a different patch of Firebush plants, some 20 m away in front of our sight field, downhill.  Then at 7:22 hrs we noticed again that a T. dupontii individual (most probable the same individual) came to the focal plant, and after foraging on 18 flowers it perched in a thin branch in front of the observed Firebush.  The bird was observed better, photographed (Figure 1) and later confirmed its identity with the help of the Howell and Webb guide (1995).    The site of observation is located 3 km north of El Limón de Cuachichinola town, in the Municipality of Tepalcingo, Morelos State, Mexico, inside the Sierra de Huautla Biosphere Reserve (SHBR; 18º 32.317' N y 98º 55.956' W; 1298 m asl).  It is covered by a mixture of altered tropical dry forest (TDF) and secondary vegetation (sites of TDF that were used for agriculture and pasture and were abandoned 7-10 years ago and are in the process of recovering).  Conspicuous tree species observed in the site are, Pseudosmodingium perniciosum (Anacardiaceae), Ceiba spp. (Bombacaceae), Bursera spp. (Burseraceae), Jacaratia mexicana (Caricaceae), Conzattia multiflora, Acacia cochliacantha, A. farnesiana, Lysiloma spp. (all Fabaceae), and Guazuma ulmifolia  (Sterculiaceae).  The site of observation is classified in the management plan of the reserve (Dorado et al. in press a) as a recovering zone, and it is surrounded by a matrix of preserved TDF.  The SHBR, is an area of approximately 60,000 has.  It is located in the northern portion of the Balsas river Basin.  The reserve it is the biggest Mexican protected area created to preserve mainly TDF and could become the most important reservoir of this vegetation type in south-central Mexico (Dorado et al. in press b).  The Sierra de Huautla region is considered a priority area for the conservation of Mexican birds (AICA; Benítez et al. 1999) where more than 170 species had been detected, nine of them hummingbirds (Ramírez-Albores and Ramírez-Cedillo 2002, Urbina 2002).  At least 20% of these species are endemic to Mesoamerica and ca. 13% are considered under some form of conservation threat by the Mexican government (Benítez et al. 1999, SEMARNAT 2002).  Present observation site of Sparkling-tailed Hummingbird in El Limón area is the first record for the SHBR, nearly 50 km to the south east of previous records for the species in Morelos state.  More observations are needed to assess if a local population of the species is established at the site.
