They build their nests in freshwater, marshes and wet meadows
The nests are usually located on a mat of floating vegetation.
Three dark brown-spotted eggs are laid and sat on by both parents for about 3 weeks
The young remain with the parents for another three to four weeks
Then they grow feathers appropriate for learning to fly
Why is the black tern on the list?
Populations have declined sharply in the past 40 years, likely due to drainage of wetlands required for nesting. Farm chemical runoff is another possible reason.
What is being done?
The Black Terns are being monitored and when the known number of species is known, their habitat is heavily protected and expanded, this can be done simply by keeping the area free of litter, introducing water to build onto the marshy area as well as keeping sure that none of the species is disturbed in any way.Like all other endangered species, the public is being educated about this bird and the way it lives and hunting is prohibited.
