“…Small numbers of Upland Sandpipers were thought to spend the nonbreeding season in northern South America (Haverschmidt, 1966;Houston et al, 1999;Blanco and López-Lanús, 2008), and our tracking data have confirmed this prediction. Finally during northbound migration, three tagged birds crossed the Andes through northern Chile, and near sites where Upland Sandpipers have recently been reported as nocturnal migrants (Medrano et al, 2018).…”

“…Little is known about migratory connectivity of this species because banding effort has been low and band recoveries are rare (Garber et al, 1997;Houston et al, 1999), and previous satellite tracking has provided information on southbound migration for a single bird (Grosselet et al, 2019). Based on specimen and natural history records, migratory routes are thought to include corridors through the Great Plains and Atlantic Coast, stopover sites in central America, and southern routes east of the Andes (Blanco and López-Lanús, 2008;Houston et al, 2011), as well as newly discovered sites along the Pacific coast of northern Chile (Medrano et al, 2018).…”

Our research protocols followed recommended procedures in the Guidelines to the Use of Wild Birds in Research of the Ornithological Council. We conducted our project under government permits for scientific research, including federal and state permits for live capture and tagging of wild birds, and access permits for working at facilities of the US Department of Defense and Konza Prairie Biological Station.

“…Listed as endangered or threatened in the U.S. (10 states and six states, respectively), and considered one of the most significant breeding shorebird species in Canada (Houston et al 2011), it is a priority species for conservation in the Americas. It breeds mainly in the U.S. Great Plains, with smaller breeding populations dispersed in Canada and Alaska, migrating south throughout Mexico east of the Sierra Madre Occidental and Central America, to its wintering grounds in South America from northern Chile and Suriname to Uruguay and Argentina (Haverschmidt 1966, Di Giacomo & Krapovickas 2005, Vickery et al 2010, Houston et al 2011, Medrano et al 2018. Pulich (1988), and Houston et al (2011), report current southernmost breeding sites from Oklahoma and formerly (before the 20 th century) from north-central Texas; there are no reproductive populations in Mexico (Howell & Webb 1995).…”

Body Condition of the Upland Sandpiper (Bartramia Longicauda) en Route Through Central Mexico

Abstract∙ There is little information on the body condition of the Upland Sandpiper (Bartramia longicauda) during migration. We measured biometric traits and body condition parameters of B. longicauda in central Mexico in 2016 and 2017. Mean morphometric values were 170.4 ± 4.3 mm (wing length), 28.9 ± 1.7 mm (bill length), 61.5 ± 2.2 mm (head length), and 55.3 ± 2.6 mm (tarsus length). Mean body condition parameters were 169.7 ± 24.1 g (body weight), and 4.6 ± 1.8 (fat score). Body condition values were higher during 2017 than 2016 (P < 0.05) but similar between sexes and sites. Fluctuating asymmetry (FA) was low compared to other studies, but was present in rectrices, tarsus, and wings. We found a negative correlation between wing FA and fat score, and a positive correlation between body weight and fat score, suggesting that birds with higher fat scores were in better condition during molt, leading to lower asymmetry. Our Data showed a 1:1.6 male:female ratio, similar across years and sites. Contrary to other studies, we found no significant sexual size dimorphism. Birds in our sample had higher body weight, tarsus, and wing length but were similar in head length to birds wintering in South America, but smaller than birds from Minnesota. We recommend carrying out further studies on stop-over sites to contribute to a better understanding of patterns on the functional ecology of the species. Resumen ∙ Condición corporal del Zarapito Ganga o Batitú (Bartramia longicauda) en ruta a través del centro de México Existe poca información sobre la condición corporal del Zarapito Ganga o Batitú (Bartramia longicauda) durante la migración. Medimos parámetros de condición corporal de B. longicauda en el centro de México en 2016 y 2017. Los valores morfométricos promedio fueron 170.4 ± 4.3 mm (ala), 28.9 ± 1.7 mm (culmen), 61.5 ± 2.2 mm (cabeza) y 55.3 ± 2.6 mm (tarso). Los parámetros promedio de condición corporal fueron 169.7 ± 24.1 g (peso corporal) y 4.6 ± 1.8 (grasa). Los valores de condición corporal fueron mayores durante 2017 que durante 2016 (P < 0.05), aunque similares entre sexos y sitios. La asimetría fluctuante (AF) fue baja comparada a otros estudios, aunque estuvo presente en rectrices, tarsos y alas. Encontramos una correlación negativa entre AF en alas y grasa, y una correlación positiva entre peso corporal y grasa, lo cual sugiere que las aves con mayores valores de grasa se encontraban en mejor condición durante la muda de plumaje, conduciendo a menor asimetría. Nuestros datos mostraron una tasa macho:hembra de 1:1.6, similar entre años y sitios. Contrario a otros estudios, no encontramos dimorfismo sexual significativo. Las aves en nuestra muestra tuvieron mayor peso corporal, tarso y longitud de ala, pero fueron similar en longitud de cabeza a aves de Sudamérica, pero menores a aves de Minnesota. Recomendamos llevar a cabo más estudios en sitios de escala para contribuir a un mejor entendimiento de los patrones en la ecología funcional de la especie.
