A few White-winged Trillers (Lalage sueurii) have turned up from down south lately. Female (above), male (below).
She's thinking food; he's frantic to attract females. Sound familiar?
Varied Trillers (Lalage leucomela) stick together and some always stick close to Tyto. So, Varieds are limited largely to coastal east and across the top but White-wingeds cover the continent. See my drift?
