Swallowtail butterfly - ‘Pilio aegeus’, found in eastern Australia and Papua New Guinea

A magical moment in the park observing this beautiful creature with my 2yr old

A little ibis appreciation, I banded this bird in 2007 as an adult (>3yrs old), so she is at least 20yrs old! The deep red colour under her wings indicates that she is breeding, is it her 20th clutch or 60th - they can breed 3 times in a season
