Nicaragua lies in the middle of the Mesoamerican isthmus, with year-round warm weather. Substantial numbers of migratory birds winter here, some of them just pass through Nicaragua during their extensive migrations in each direction, and a few species of birds nest here and then migrate southward during the non-breeding period.
Other birds, such as the pictured Chestnut-capped warbler (Basileuterus delattrii), are strictly resident species. That means that they never move particularly far from the area where they were born, possibly only excepting what is called dispersal, which occurs as birds mature and depart from parental assistance. Of the more than seven hundred bird species documented in Nicaragua, about a third of them are found in Laguna de Apoyo Nature Reserve. One of the more important bird species there is the Chestnut-capped Warbler.
Birds from this location have been reported in a pair of scholarly articles on new and novel reports of birds in Nicaragua. In the first of the two new bird species reports, co-authored by Wayne J. Arendt, Salvadora Morales, Joseph T. Arengi and Lorenzo J. Lopez, first documentations in the scientific literature for ten species were given: Fulvous Whistling-Duck (Dendrocygna bicolor), Nazca Booby (Sula granti), Long-billed Dowitcher (Limnodromus scolopaceus), Snowy Plover (Charadrius alexandrinus), Wilson’s Plover (Charadrius wilsonia), Marbled Godwit (Limosa fedoa), Sanderling (Calidris alba), Baird’s Sandpiper (Calidris bairdii), among others.
