Hello everyone,

As an ornithology grad student who was breeding tropical birds as a hobby,
i remember asking this question of my advisor.

A paper just came out in SCIENCE that explains the reasons why tropical
songbirds produce fewer chicks per breeding attempt than do temperate
songbirds. In this amazing paper, the author, Tom Martin from the
university of Montana, draws upon several decades of field work in Arizona,
Venezuela and Borneo to support his hypothesis. The paper itself is
amazing, although it's short, it sheds light on our fuzzy understanding of
breeding bird biology, it corrects several long-held misunderstandings, and
adds valuable information to our understanding to the subtle interplay of
ecology and evolution.

Life history trade-offs: why tropical songbirds have fewer chicks

i hope you enjoy the story i wrote about this important breakthrough. i
also hope you share it with your colleagues, friends, and family, and of
course, on social media and twitter.

tsch?ss.
