Abstract

In the report "Honeyguides and honey gatherers: Interspecific communication in a symbiotic relationship" by H. A. Isack and H.-U. Reyer (10 Mar., p. 1343), the third and fourth sentences of the first full paragraph of column 2 on page 1344 should have read "This whistle, known in Boran language as " Fuulido ," is produced by blowing air into clasped fists, modified snail shells, or hollowed-out doum palm nuts ( Hyphaene coriacea Gaertn.) Shouting and knocking on dry wood are also used to draw the birds' attention."
