NEW PAPER: Despite similar morphology, eastern and western northern house wrens show nuclear and mitochondrial genomic differentiation. A contact zone in Colorado suggests hybridization, with weak population structure. ➡️ vist.ly/3mxxjvy #ornithology #speciation #birds

NEW PAPER: Whimbrel display behavior varies by breeding density and season. Higher display frequency at low densities pre-incubation suggests mate attraction, while resource defense may be important throughout. ➡️ vist.ly/3my7jty #ornithology #bioacoustics #shorebirds

NEW PAPER: goldeneye breeding start has advanced with climate change, driven by ice breakup, while nest predation affects the end of breeding. Longer breeding periods and lower offspring survival highlight complex climate impacts ➡️ vist.ly/3myeqx8 #ornithology #climate

NEW PAPER: Migrating common snipes in better condition show stronger immune responses, suggesting high-quality individuals maintain immunity. Abundant food at stopovers may help replenish reserves for immunity. ➡️ vist.ly/3mzcari #ornithology #migration #EcoImmunology

NEW PAPER: exploring variation in wing and tail moult in >2400 white-chinned petrels. Large sample size reveals considerable variation among individuals, which is surprising given the high cost of moult. ➡️ vist.ly/3m2d42v #ornithology #moult #seabirds

NEW PAPER: linking carotenoid-derived plumage colour to diet, condition and heterophil/lymphocyte ratio in a Neotropical bird reveals sex differences that appear to be due to different foraging strategies. ➡️ vist.ly/3n3h6u5 #ornithology #birds #diet #StableIsotopes
