BLANCAS-CALVA, Epifanio; CASTRO-TORREBLANCA, Marisol  and  BRISENO-HERNANDEZ, Iván. Sandwich Tern (Thalasseus sandvicensis) on the coast of Guerrero, Mexico. Huitzil [online]. 2019, vol.20, n.1, e381. ISSN 1870-7459.  https://doi.org/10.28947/hrmo.2019.20.1.381.

New species records strengthen knowledge of biodiversity and are evidence that understanding of biodiversity is still partial, especially in areas where diversity is high. It is important to continue collecting information that contributes to strengthening the knowledge of biota and the benefits derived from it. In this study we recorded the Sandwich Tern (Thalasseus sandvicensis) at two locations on the coast of Guerrero. The first locality was at Carrizal de Cinta Larga, municipality of Tecpan de Galeana, on February 2010, December 2012, August and December 2013 and January 2015. The second location was in Casa de Piedra beach, municipality of Marquelia, on December 2011. The species is not included in the avifaunistic list of Guerrero. Our records confirm the presence of the species at these locations.
