Lesser Adjutant vs Marabou Stork

Lesser Adjutant

Leptoptilos javanicus

Huge4.7 kgWetland

A large stork with an upright stance, a bare head and neck without a pendant pouch, it has a length of 87–93 cm (34–37 in) (outstretched from bill-to-tail measurement), weighs from 4 to 5.71 kg (8.8 to 12.6 lb) and stands about 110–120 cm (43–47 in) tall. The only confusable species is the greater adjutant, but this species is generally smaller and has a straight upper bill edge (culmen), measuring 25.8–30.8 cm (10.2–12.1 in) in length, with a paler base and appears slightly trimmer and less hunch-backed.

Leptoptilos crumenifer

Huge6.1 kgGrassland

The marabou stork is a massive bird: large specimens are thought to reach a height of 152 centimetres (5 feet) and a weight of 9 kg (20 lb). A wingspan of 3.7 m (12 ft) was accepted by Fisher and Peterson, who ranked the species as having the largest wing-spread of any living bird. Even higher measurements of up to 4.06 m (13.3 ft) have been reported, although no measurement over 3.20 m (10.5 ft) has been verified.
