Behavior Patterns
Jabiru
Social Structure
Generally solitary or seen in pairs, though small groups may form around abundant food sources.
Song and Vocalization
Silent for the most part, though it may produce low bill-clattering sounds, especially during courtship or when alarmed.
Courtship and Mating Ritual
Courtship involves synchronized bill-clattering and mutual preening between the pair. They often return to the same nesting site year after year.
Territoriality
Jabirus are territorial during the breeding season and will defend their nesting areas from other storks.
Birdwatching Tips
Best Locations for Spotting Jabiru
Some of the best spots to see Jabiru in Costa Rica:
- Palo Verde National Park in Guanacaste is one of the best locations to observe Jabirus.
- Caño Negro Wildlife Refuge is another prime site, especially for wetland birdwatching.
Best Time of the Year
Year-round, though the dry season (December to April) is the best time to spot Jabiru Stork as wetlands shrink, concentrating bird activity.
Common Behavior
Look for them in wetlands and marshy areas, where they can often be seen wading slowly in shallow water in search of food.
Recommended Gear
A spotting scope is ideal for long-distance viewing, as Jabirus often feed far from shore. Binoculars and a good telephoto lens are also recommended.
Breeding and Nesting Behavior
Breeding Season
In Costa Rica, the breeding season is during the dry months, from December to May.
Nesting Sites
Builds large, platform nests high in trees, often near wetlands. The nests are constructed from sticks and lined with softer materials.
Clutch Size
Typically 2-4 eggs.
Incubation Period
Parental Care
Both parents share duties in incubating the eggs and feeding the chicks after hatching.
