Bird number 187 on my life list is the Black-tailed Native-hen.
I saw a single bird at the Peninsula Ornamental Gardens in Maylands after a tipoff from the Birds WA sightings page. On two consecutive days I located the bird within 5 metres of the same spot. It seems to prefer foraging along the scrub/lawn edge where it can quickly duck for cover if disturbed.
Thanks to Peter Clifton for finding it!
