ハグロツバメチドリ Glareola nordmanni

Similar to other pratincoles, the Black-winged Pratincole is an elegant shorebird of dry habitats, not necessarily mud. Very similar to Collared Pratincole, but in flight lacks whitish wing trailing edge seen on Collared and the underwing feathers are black not rufous. Note however, that both of these features may be very difficult to notice in the field, depending on light conditions. When standing its legs are longer and tail shorter, resulting in primary feathers projecting beyond the tail tip, but beware of Collared Pratincoles molting their elongated outer tail feathers. Flight call is very similar to Collared Pratincole, but slightly lower-pitched.
