Northern Jacana
Northern Jacana
Jacana spinosa
At a Glance
At marshy ponds from Mexico to Panama, this odd shorebird is common. Its long toes allow it to run about on lily pads and other floating vegetation. When it flies, the feet trail behind it; on landing, it may hold the wings high for a moment, showing off the yellow flight feathers. This species has turned up several times in Texas, and has even nested there.

Behavior
Eggs
Usually 4, sometimes 3-5. Almost round; brown, scrawled with black lines. Incubation is by male only, 22-24 days. During hot part of day, male will shade eggs from sun (female occasionally shades eggs also).
Young
Downy young leave nest within 1-2 days after hatching. Male tends young and leads them to feeding sites, but young feed themselves; male broods young during rain or cool weather. Female sometimes accompanies or broods young, but always far less than male. Age at first flight about 4 weeks.
Feeding Behavior
Forages by walking about on mats of floating vegetation, picking insects from surface of plants or water, sometimes from just below water's surface. Also forages on mud or open ground near water.
Diet
Mostly insects. Diet in Texas not well known. In Costa Rica, reported to feed almost entirely on insects; occasionally eats small fish.
Nesting
One female may have up to 4 mates; she lays eggs in separate nests for each, and males do almost all the work of incubating the eggs and caring for the young. Nest site is on top of marsh vegetation, either standing or floating, in shallow water. Nest (built by male) is a flimsy and simple open cup made of available plant material; male continues to add to nest during incubation period.
Conservation
Conservation Status
Very common in parts of its normal range, but could be vulnerable to loss of wetland habitat.
