Sheer Speed of Global Warming Is Decimating Birds, Say Scientists

https://www.haaretz.com/science-and-health/MAGAZINE-sheer-speed-of-global-warming-is-decimating-birds-say-scientists-1.6302093

Paper: Rapid warming is associated with population decline among terrestrial birds and mammals globally

https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.14361


The points show the distribution and density of population time series used in the analysis. The black and white points signify bird and mammal populations, respectively, where both taxonomic groups are present the numbers of each are proportionally represented with a pie chart. 77.4% of the locations have one population. The base layer of the map shows the rate of temperature change, in degrees per year, between 1950 and 2005, based on analysis of the CRU TS v. 3.23 gridded time series dataset (Harris et al., 2014)

Should you share data of threatened species?

The Night Parrot (Pezoporus occidentalis), was recently rediscovered in the arid zone of Australia. Exact population locations were kept secret to prevent the birds being disturbed by eager bird watchers or targeted by poachers. Historical published data is helping conservation managers to better understand the species.

Among golden-crowned sparrows, a false crown only fools strangers

https://www.sciencedaily.com/releases/2018/07/180725064535.htm?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+sciencedaily%2Fplants_animals%2Fbirds+%28Birds+News+--+ScienceDaily%29


The brightness and coloring of the plumage on the heads of golden-crowned sparrows is highly variable. The patches of yellow and black plumage on the birds' heads serve as "badges of status," signals that correlate with fighting ability and allow birds to figure out who is dominant without having to fight.
