April 1-7 2004
Hello,

The following is the first installment of the weekly synopsis of Migration
Monitoring at Tommy Thompson Park in 2004.

Spring Migration Monitoring in 2004 began on April 1st with a fully
standardized protocol. For the week of April 1st-7th, landbird migration
has been very weak with only a trickle of migrants detected on a daily
basis. Song Sparrow, Winter Wren, Brown Creeper and Golden-crowned
Kinglet are the dominant species thus far. Waterbirds have been present
in high numbers as one would expect for this time of year on Lake
Ontario. Double-crested Cormorants and Black-crowned Night Herons
have just started to appear in the past weak and are increasing with each
passing day. Weather for the period has been wet and cold with primarily
Northerly winds, which has hampered the migration of landbirds.

Highlights:
