Treecreeper (Certhia familiaris)
Little Egret (Egretta garzetta)
Unmistakable, except in areas where it coexists with Short-toed Treecreeper. Differs from said species in pure white flanks (sub-species macrodactyla has faintly buff flanks but not as marked as in Short-toed), shorter and only moderately curved bill, hind-claw as long as hind-toe and "notched" wing-bar (uneven "steps"). Tips of primaries with buffish/white tips/fringes extending along inner web. Mostly distinguished from Short-toed by call, and identification exclusively by plumage characters difficult in areas where both species occur.
Sound:Contact call a drawn, high-pitched "tzreeee". Similar to Goldcrest in timbre, but of longer duration with a vibrating and slightly rolling tone. Generally repeated in evenly paced, slow series (unlike Goldcrest). Song a short, continuous three-part phrase. Each phrase starts with a few contact call-like notes followed by a Willow Warbler-like descending part, which then jumps to a few descending high notes to form a marked conclusion. Note that "mixed singers" are not uncommon in areas where both species of treecreepers occur.

CCDiffers from other white herons in the region by dark legs with contrasting yellow feet and toes. Bill always dark, and lores grey or reddish (breeding birds). Slender and elegant build, as opposed to Cattle Egret. Only roughly half the size of Great White Egret. In flight, note much quicker wing-beats of Little Egret and that the wings of Great White seems to be positioned more at the front of the body. Skulking, foraging behaviour with less erect posture than Great White, also when moving about. Legs less protruding beyond tail in flight than in GWE.
Sound:Sometimes utters a dry, rasping "kerrr" when flushed, but is mostly silent away from breeding ground. In colonies a peculiar gurgling and vibrating sound is heard; "ghala-la-la-la".
