New research examines the accuracy of information produced by citizen science apps for monitoring bird populations and found that it could actually offer a lot of utility for researchers, with some caveats.

While it is firmly established that Eurasian penduline tits bury them because of sexual conflict, their Chinese counterparts seem to have an entirely different reason. Experimental manipulations show that for these birds burial prevents the eggs from falling out of the nest in […]
