“…Indeed, when the constant-environment rooms overheated one night, maintaining a T a of 43°C and 39°C for ∼16 h in the control+4°C and control groups, respectively, only 2 of the 22 birds expired. That most of the birds could survive something akin to an 'extreme heat event' is testament to their great physiological flexibility, and this, along with their generalist feeding habits (Fry et al, 2000) and their use of a wide range of habitats (Hulley et al, 2004;Smith and Bowie, 2005), should be in their favour in the face of ongoing anthropocentric climate change (Jiguet et al, 2007;Julliard et al, 2003;Knowlton and Graham, 2010;Schwartz et al, 2006;Thomas et al, 2004).…”
