Abstract We used data collected across 28 years (1975–2002) to compare how timing of laying and egg size respond to environmental variability in two low-arctic and two high-arctic Thick-billed Murre (Uria lomvia) populations. Ice conditions strongly affect food availability to marine birds in the Ar...
