“…We used the digital database ORNIS (http://www.ornisnet.org/) to search for Rufous‐thighed Kite specimens held in 33 North American institutions, requested specimen data from the Museu de Zoologia Universidade de São Paulo, São Paulo, Brazil (MZUSP), and the Museu Nacional Rio de Janeiro (MNRJ) and visited the collections of the Museu Paraense Emílio Goeldi, Belém, Brazil (MPEG), and the Natural History Museum at Tring, UK (NHM), to look at specimens. Collecting localities were located using Paynter (, , , , ), Paynter and Traylor () and Stephens and Traylor (). This search of museum collections was accompanied by a review of previous published ornithological inventories listing Rufous‐thighed Kites from South America (see literature list in Supporting Information Appendix S1), a request for data from eBird http://ebird.org/ and an extensive search for digital vouchers archived online, images on WikiAves, Fauna Paraguay http://www.faunaparaguay.com and the Internet Bird Collection http://ibc.lynxeds.com/ and sound recordings on xeno‐canto http://www.xeno-canto.org and the Macaulay Library http://macaulaylibrary.org/.…”

Gaps in our knowledge of the geographical distribution of species represent a fundamental challenge to biogeographers and conservation biologists alike, and are particularly pervasive in the tropics. Here we highlight the case of the Rufous-thighed Kite Harpagus diodon, a South American raptor commonly mapped as resident across half the continent. Recent observations at migration watch points have indicated it may be partially migratory in the southernmost parts of its range. To investigate this possibility, we collated contemporary and historical specimen records, published sight records and 'digital vouchers'photographs and sound-recordings archived online (from citizen science initiatives)and explored the spatiotemporal distribution of records. We were unable to trace any documented records of this species from Amazonia during the austral summer (October-March), or records from the Atlantic Forest biome during the peak of the Austral winter (June-August), and all proven breeding records stem from the Atlantic Forest region. We compared this pattern with that of a 'control' species, the congeneric Double-toothed Kite H. bidentatus, again using specimens and digital vouchers. For this species we found no evidence of seasonality between biomes and can disregard spatiotemporal variation in observer effort as a cause of seasonal biases. We consider that all populations of Rufous-thighed Kites are fully migratory, wintering in Equatorial forests in the Amazonian basin. We provide evidence that this pattern was previously obscured by erroneous undocumented records and poor or erroneous specimen metadata, and its discovery was primarily facilitated by digital vouchers. This discovery requires a reassessment of the species' global conservation status as an Atlantic Forest breeding endemic, threatened by habitat loss and degradation, as it was previously considered to be resident across large swathes of undisturbed Amazonian Forest on the Guiana Shield. The bulk of the digital voucher data used to elucidate this pattern were extracted from a Brazilian citizen science initiative WikiAves, which may serve as a model for collating biodiversity data in megadiverse countries and help catalyse environmental awareness.

“…We obtained ornithological collection localities from the ornithological gazetteers of the Neotropics (Paynter, 1982, 1988, 1989, 1992, 1993, 1994, 1995, 1997; Stephens & Traylor, 1983, 1985; Paynter & Traylor, 1991; Vanzolini, 1992). These gazetteers provide geographical coordinates for ornithological collection localities, compiled from the literature and museum collections.…”

Across‐taxa incongruence in patterns of collecting bias

If biological collections tend to be taken near accessible areas, and the number of such areas is limited, then we should expect a similar spatial distribution of collecting effort across taxa. Alternatively, if researchers working on a given taxon pick collection localities based on idiosyncratic criteria, then there should be no spatial similarity in collecting effort. This study compares the spatial distribution of collecting effort for plants and birds in Amazonia. Collection localities were transformed into a Thiessen network where polygon size works as a surrogate for collecting effort. A correlation between botanical and ornithological datasets, with an adjustment for spatial autocorrelation, showed little congruence in the spatial distribution of collecting effort between the two taxa. This incongruence of the distribution of collection effort among taxa suggests that the identification of priority areas for research, and correction for Wallacean and Linnean shortfalls based on taxon‐specific studies, should not be generalized.

“…Each record was georeferenced (i.e., latitude and longitude coordinates were attributed to the locality) using maps, databases and gazetteers. For the historical records and those localities that had their names changed, we used the Ornithological Gazetteers from South America [Paynter, 1975[Paynter, , 1977[Paynter, , 1981[Paynter, , 1982[Paynter, , 1983[Paynter, , 1985a[Paynter, , b, 1988[Paynter, , 1989[Paynter, , 1991[Paynter, , 1994. Those localities with only vague geographic information were not considered.…”

Cognition in an Ever-Changing World: Climatic Variability Is Associated with Brain Size in Neotropical Parrots

Research on the conditions favoring the evolution of complex cognition and its underlying neural structures has increasingly stressed the role of environmental variability. These studies suggest that the ability to learn, behave flexibly and innovate would be favored under unpredictable variations in the availability of resources, as it would enable organisms to adjust to novel conditions. Despite the growing number of studies based on the idea that larger-brained organisms would be better prepared to cope with environmental challenges, direct testing of the association between brain size and environmental variability per se remains scant. Here we focus on Neotropical parrots as our model group and test the hypothesis that if relatively larger brains were favored in climatically variable environments, larger-brained species should currently tolerate a higher degree of environmental uncertainty. Although we show that there are also other factors underlying the dynamics of brain size variation in this group, our results support the hypothesis that proportionally larger-brained species are more tolerant to climatic variability, both on a temporal and spatial scale. Additionally, they suggest that the differences in relative brain size among Neotropical parrots represent multiple, recent events in the evolutionary history of the group, and are particularly tied to an increased dependence on more open and climatically unstable habitats. As this is the first study to present evidence of the link between brain size and climatic variability in birds, our findings provide a step towards understanding the potential benefits underlying variation in brain size and the maintenance of highly enlarged brains in this and other groups.
