In the marshes around America’s spaceport, Kennedy Space Center, live the last few specimens of a bird that may be closer to extinction than even the much-mourned whooping crane. While the whooper might make a gradual comeback if protected and left alone, the dusky seaside sparrow is as good as dead unless man steps in to lend an active hand. — Science News, May 25, 1968.
Conservation efforts have kept whooping cranes around. Dusky seaside sparrows (Ammodramus maritimus nigrescens) were not so lucky. The population tanked when efforts to flood out mosquitoes breeding near the space center along with construction destroyed the birds’ nesting grounds. By 1968, scientists knew of only 17 males. Attempts in the 1980s to breed captive males with females of a different subspecies created a few hybrids. But researchers discontinued the program when the last known dusky, named “Orange Band” for the tag on his leg, died in captivity at the Walt Disney World Resort in 1987.
