This study examines how subtle temperature changes during early life affect gut microbiome diversity and composition in wild birds, finding that rearing environment has a greater influence than genetics.

Both experimental nestbox heating (+2.83°C) and cooling (-1.72°C) during early postnatal development significantly shorten day-13 relative telomere length in wild pied flycatcher nestlings without altering body mass.

The paper shows that early-stage altricial bird embryos express genes involved in thyroid hormone pathways, suggesting they can respond to maternal thyroid hormone signals.

This study shows that maternal thyroid hormone transfer increases nestling growth without increasing oxidative stress in a wild passerine bird.
