| The Black Tern
ranges from British Columbia south to central California and east as far as New Brunswick
and south to New York. They winter along both coasts from Panama south to Peru and
Surinam. The population has been declining in recent decades due largely to loss of
wetland habitat. Reduced hatching success in the upper Midwest can be attributed,
with little doubt, to agricultural chemicals. Nests are built in emergent
vegetation. Sometimes elaborate, most float on a mat of damp vegetation raising the eggs just above the
water. This causes the nest success to be low. Coupled with the effects of chemical
runoff, the overall survival of this beautiful bird becomes a concern. |
