To lead me away from her nesting site most likely!
It’s not too hard to find Lesser Yellowlegs in interior Alaska during the summer months if you get a ways out of town near some water. And you’ll know you found one when you hear that mind-numbing “TU TU TU” alarm call. (You can hear it here.)
The Greater Yellowlegs – a larger version of this bird – also visits Alaska in the spring and summer, but doesn’t come this far north. In the winter, Yellowlegs sandpipers can be found in Mexico and the coastal and southern edge of the U.S.
They eat aquatic insects, snails, & small fish, nest in depressions in the ground in bogs and treeless tundra, and give birth to 4 eggs which when hatched are precocial which means they can fend for themselves as soon as their natal down is dry.
It’s hard to believe, but people used to hunt sandpipers like these! These skinny little birds were game species and apparently market hunters nearly wiped out many types of shorebirds before they were protected in the early 1900s. Thank goodness!!!
