How do you protect two rare birds when one keeps attacking the other?
Plans to repopulate Hawaii’s forests with its “very intelligent” crows have been upended in part by its natural predator, the Hawaiian hawk. Now scientists are tracking the hawk in order to save the corvids.
Amy Durham wound the straps under the wing, over the wing, under the other wing, over the other wing, making sure the backpack-like device stays comfortably strapped to the Hawaiian hawk for many months.
“This may be your best work yet,” said Diego Johnson, one of her colleagues holding the straps on the chocolate-colored hawk’s chest as Durham secured a lightweight GPS transmitter to its back.
These San Diego Zoo researchers are trekking around the mountainous jungles of Hawaii’s Big Island not just to understand the ‘io, one of the state’s only birds of prey, which is considered at risk. It’s crucial, too, for restoring an even more endangered bird species — the ‘alalā, or Hawaiian crow.
Known for its problem-solving abilities, the Hawaiian crow is one of the most remarkable bird species in the world. The ‘alalā, whose name means to “yell” in the local language, is one of the only birds in the world known to naturally use — and even make — its own tools.
Yetthis distinctive crow that many dub “very intelligent” has beenextinct in the wild for two decades, with the only about 120 alive in human care today.
