On this page, we ask for information regarding bird species listed as DD. In particular, we are interested in anything related to the conservation status of these species, i.e. the population size, population trend and geographical distribution. Furthermore, information on behaviour and ecological requirements can provide important evidence and help resolve the threat status. To contribute information on any of the birds listed as DD, please comment below.
There is slightly newer information available on our 2015 HBWAlive account (now on BoW) https://doi.org/10.2173/bow.whfswi1.01 and a better stab at a population estimate than the implausible PiF figures here https://www.researchgate.net/publication/321882971_Photographs_sound_recordings_and_status_of_White-fronted_Swift_Cypseloides_storeri_a_poorly-known_Data_Deficient_Mexican_endemic
Many thanks for providing information on Data Deficient species. We will analyse and interpret the new information to assess the suitability of the topic; if appropriate we will initiate a new discussion during the upcoming Red List update.
