Earlier colony arrival but no trend in hatching timing in two congeneric seabirds ( Uriaspp.) across the North Atlantic
A global analysis recently showed that seabird breeding phenology (as the timing of egg-laying and hatching) does not, on average, respond to temperature changes or advance with time (Keogan et al. 2018 Nat. Clim. Change 8 , 313–318). This group, the most threatened of all birds, is therefore prone...
