African Openbill vs Jabiru

African Openbill

Anastomus lamelligerus

Large1.1 kgWetland

The African openbill is a stork measuring 80–94 cm (31–37 in) and weighing 1–1.3 kg (2.2–2.9 lb). The species does not exhibit any major sexual dimorphism, although the males are slightly larger than the females and have a longer and heavier bill. The adult bill is between 135–196 mm (5.3–7.7 in) in length, brownish in color and has a gap between the upper and lower mandible. This gap is non-existent in juvenile birds and develops as the bird ages. It is because the two mandibles of the beak only meet at the tip and not in the middle that this stork genus received the name of "openbill". Voice: Many of the social displays of the African openbill stork are accompanied by bill clatters as is common in most of the Ciconiidae species. This bird also croaks and honks loudly.

Jabiru

Jabiru mycteria

Huge6.0 kgGrassland

The jabiru is the tallest flying bird found in South America and Central America, often standing nearly the same height as the flightless and thus much heavier greater rhea. For the continent, it also has the second largest wingspan, after the Andean condor (that is, excluding the great albatross occasionally found off the coast of southern South America). The adult jabiru is 120–140 cm (47–55 in) long, 2.3–2.8 m (7.5–9.2 ft) across the wings, and can weigh 4.3–9 kg (9.5–19.8 lb). Sexual dimorphism is high, possibly the highest of any stork, with males being about 25% larger than females.
