“…In recent years, numerous cases of latitudinal, longitudinal, and altitudinal movements of waterbirds have been reported, both in Ecuador [58,79,80] and in the Neotropics [55]. The movements of these species may be influenced by different events, such as the El Niño-Southern Oscillation (ENSO) phenomenon [81], the pollution of natural wetlands, or the disappearance and appearance of new artificial bodies of water [82]. The only terrestrial species classified as a change of distribution is the White-tailed Kite (Elanus lecurus), a raptor that is benefiting from deforestation in the Tumbesian region [83] and is expanding its range to the south, along the Pacific coast.…”

Knowledge Gaps or Change of Distribution Ranges? Explaining New Records of Birds in the Ecuadorian Tumbesian Region of Endemism

et al. 2020

The change in the distribution range is a common response of various species facing the effects of anthropogenic global change. We used new distribution records of birds reported during the last two decades from the Ecuadorian part of the Tumbesian region (western Ecuador and northwestern Peru) available through a bibliographic review, together with our own field data collected during 2014–2019, and generated a methodology that explored whether these new reports are likely due to knowledge gaps or changes in the distribution range. We classified the species with new records as either Change of distribution range, Likely change of distribution range, Accidental, Knowledge gap, or Undetermined based on information about the distribution area, species conspicuousness, and dynamics of the records in the new location. We gathered data for 46 bird species newly reported in the Ecuadorian Tumbesian region in the last two decades. Of this, 35% of species were classified as Accidental, 24% as Knowledge gaps, 22% as Change of distribution range, 15% as Undetermined, and 4% as Likely change of distribution range. Species classified as Change of distribution range were mostly aquatic. Terrestrial species were mostly classified as Knowledge gap, while aquatic species were mostly classified as Accidental. Our protocol was validated using species which are known to have modified their distribution range in the Palearctic region, all of which were correctly classified by our methodology. The proposed method was precise and easy to apply and will allow us to better understand how species respond to anthropogenic global change, especially in areas where long-term studies are scarce, such as in tropical areas.

“…Although the reason for this recent range expansion is currently unknown, we speculate that anthropogenic disturbances such as land-cover changes and climate change are likely important factors to consider. Indeed, a growing number of studies have also associated range expansion in Neotropical birds with these factors in both lowland and montane species (Sandoval et al 2017;Freeman et al 2018). Thus, the detailed collection and publications of sighting records of the Gray-capped Cuckoo throughout the region will be crucial to test this possibility.…”

This note presents the first record of Coccyzus lansbergi (Bonaparte, 1850) for the southwest coast of Panama. This new record was made on July 11, 2018, in the rural community of Juan Hombrón, Coclé province, Panama. The species has been previously observed in eastern Panama, but this is the first record for the southwestern region of the country. Our record is at least 142 km southwest of its nearest reports in eastern Panama. Overall, this record indicates that the species is likely a vagrant from its known range, given that no other records have been documented south of Coclé, in Panama. In addition, the increasing number of records from eastern Panama over the last 30 years suggests a recent expansion in the northern range of the species.

“…Por lo tanto, se hace necesario un mayor esfuerzo en el reconocimiento y la efectiva identificación de los taxones de este grupo, del cual se sabe que ha radiado en cientos de especies desde el mioceno (Futuyma 1997;Chaves et al 2008;Harvey et al 2020). Por su parte, el complejo M. cayanensis ha sido estudiado en diversas áreas de la biología como la ecología reproductiva, estrategias de forrajeo, anidamiento, morfología general, comportamiento agonístico, ectoparásitos, uso del hábitat, historia natural y distribución, entre otros (Haverschmidt 1971;McKitrick 1985;Cruz y Andrews 1989;Dyrcz 1991Dyrcz , 2002Davis 1993;Rowlett 2003;Price et al 2005;Screnci-Ribeiro y Duca 2010;Watson 2012;Smith et al 2014b;Sandoval et al 2018), pero poco se conoce sobre el estatus taxonómico de sus poblaciones actuales. Debido a su gran similitud, M. cayanensis es usualmente confundido con M. similis en las listas de registro, lo cual crea ruido en los registros actuales de distribución y abundancia.…”
