Rufous Fantail (Rhipidura rufifrons) in Australia by Tim Siggs. 

Remember these three birds I drew? Here they are in action, illustrating demographic information for their respective species in PLOS One!

In brief summary of the above graphs, Rufous Fantails produce more offspring when both the wet season and dry season are wetter than average, while both white-eye species do well when there’s a sharp contrast between how wet the two seasons are, whether it’s a dry wet season and a wet dry season, or vice versa. Overall though, Bridled White-eyes don’t show a very extreme response, while Golden White-eyes seem to be much more responsive to these variations in yearly climate.
