“…The literature suggested that egg sample size varied considerably among different studies, e.g., egg sample sizes of little egret varied between three and five per heronry (Keithmaleesatti et al 2007), 12 eggs from brown boobies at eight colonies from the northern Gulf of California to southern Mexico (Mellink et al 2009), five to 15 eggs per heronry in the study of Henny et al (2003), three to five eggs per colony of great blue herons (Ardea herodias) from Indiana (Baker and Sepu'lveda 2009), three to 14 eggs of little egrets from three breeding heronries of three selected wetlands of Pakistan (Sanpera et al 2003), five to 11 eggs from two cattle egret heronries from south Africa (Bouwman et al 2008), and 20 eggs of cattle egrets from Tai Lake in China (Dong et al 2004). Therefore, in this study, from each heronry, a total of 10 nests were sampled, and one egg from each nest was collected.…”

“…Además, debe mencionarse que en las muestras recogidas en 2006 de huevos de bobos café en el Pacífico mexicano y el Golfo de California, incluidas las islas Marietas, se determinó un nivel bajo de compuestos de metabolitos de organoclorados (diclorodifenildicloroetileno o DDE), lo que se consideró un signo de ecosistema marino costero saludable. Las concentraciones encontradas no están relacionadas con el adelgazamiento de la cáscara del huevo y, por tanto, no ponían en riesgo la eclosión ni el éxito reproductivo (Mellink et al, 2009). Los compuestos organoclorados en las Marietas se relacionaron entonces con los insumos utilizados para el control de mosquitos tanto en Puerto Vallarta como en la Riviera Nayarit.…”

“…La mayor parte de estos estudios se ubican en las zonas costeras del Pacífico Norte. En este sentido, Mellink et al (2009) detectaron DDE (0.053 µg/g base húmeda) en huevos de bobos cafés (Sula leucogaster) de las islas San Jorge y San Pedro Mártir en Sonora. En la isla Peña Blanca, Colima, se detectaron concentraciones menores a 0.01 µg/g y de acuerdo a los autores, el grosor del cascarón no se vio afectado por las concentraciones de DDE.…”
