Three subspecies of one species, Ammospiza Maritima. One is extinct, the dusky seaside sparrow. The others are the seaside and Cape Sable seaside sparrows.
The dusky seaside sparrow had many predators,including,snakes and cats,raccoons,and foxes.But the main reason for the loss of this race of the seaside sparrow was the loss of its habitat which were marshes near Titusville,Florida.The last one died in 1987.
They cheep at one another may also display when mating.
Did they practice fighting? Yes. They trained as soldiers, and would compete with one another.
education differences
no sparrows do not eat robins. Why would any one ask such a question anyway?
To contend emulously; to seek or strive for the same thing, position, or reward for which another is striving; to contend in rivalry, as for a prize or in business; as, tradesmen compete with one another.
I guess when they're running out of resources.
Sadly, the only place you can see a Dusky is in a few museums or photographs. (See the link below.) The Dusky seaside sparrow was a local subspecies of the seaside sparrow that lived in the salt marshes of the St. John's River and Merritt Island, Florida. Duskies rarely traveled more than two miles during their lifetimes, and by 1983 they were seriously depleted due primarily to DDT poisoning and habitat destruction. In late 1983 the last four living Dusky seaside sparrows were taken to Walt Disney World Resort, to continue crossbreeding and living out their days in a protected habitat on the Discovery Island nature reserve. The last one died on June 17, 1987 at the ripe old age of 8 years. Dusky seaside sparrows were declared extinct in December of 1990.
They will not compete with one another for food
Because it's in our nature to compete and challenge one another.
