Lo designa como: “The Everglade Kite is common in the Cienaga where Ampullarias abound. It also is usually to be seen about Lake Ariguanabo, and was reported by Gundlach from ponds in the Cauto Valley. My old companion, Fermin Cervera, a former Spanish soldier now resident in Cuba, wrote me that on May 12, 1915, he shot four "snail hawks," and on the same day found two nests, each containing their eggs. Those of one nest were almost ready to hatch, those of the other recently laid. Both nests were in a willow (Clavellina) tree in the middle of Lake Ariguanabo and were about a yard and a half above the water-level. The nests were well made of twigs and grasses. The eggs are now in the Museum of Comparative Zoology, and are the first recorded for this bird from Cuba, for Gundlach never found it breeding. It comes and goes in a most inexplicable manner, and often on visits to Ariguanabo I have not seen a bird. |
“Its flight is singularly like a Marsh Hawk's, only more flapping and labored. As is well known, its sole food consists of Ampullarias, snails which from dusk to dawn often swim with the foot expanded, hanging from the surface film of the water. The bird feeds at morn and eve, and has its regular stations where the snails are skilfully shucked unbroken, and where the heaps of shells accumulate and last many years. The Kites inevitably are growing rarer in Cuba, as in Florida, for draining goes on apace.” |
