PEREZ ARTEAGA, Alejandro; MONTERRUBIO RICO, Tiberio; HUACUZ ELIAS, Dolores del Carmen y HERRERIAS DIEGO, Yvonne. Nests and broods of Mexican Duck (Anas diazi) in Penjamo, Guanajuato, Mexico. Acta univ [online]. 2019, vol.29, e1910. Epub 05-Nov-2019. ISSN 2007-9621. https://doi.org/10.15174/au.2019.1910.
Seven nests of the Mexican Duck (Anas diazi) from Penjamo, Guanajuato, Mexico are described. The nearest nest-to-water body distance ranged from 100 m to 800 m; the nearest distance to standing water ranged from 150 m to 1200 m; the nesting cover was between 50 cm to 130 cm tall. Nests were mostly of a low-cup lateral and well-concealed type. External dimensions ranged from 25 cm to 45 cm × 20 cm to 33 cm, 0 cm to 13 cm tall; internal dimensions ranged from 17 cm to 36 cm × 9 cm to 20 cm. The primary nest material was wheat stubble, and the secondary material was Bouteloua-sorghum. When found, clutches consisted of 1-6 eggs, including viable (n = 2), poached (n = 1), abandoned (n = 2) and successful (n = 1) eggs. Observed broods (n = 6) had between 3 and 9 ducklings found over and up to 400 m from the standing water. Due to the scarcity of available information on the species, these results contribute to its knowledge on the most important distribution area.
