Migration Monitoring at TTP-April 8-14


Swamp Sparrow (Dan Derbyshire)
April 8-14 was an "up-and-down" week at Tommy Thompson Park. Calm conditions on April 8 failed to produce any major bird numbers as only 17 birds were banded. Glaucous Gulls were still being seen in decent numbers as 12 were spotted on what was left of the ice in the embayment. Significant movements of migrants were evident on both the 9th and 10th as 61 and 142 birds were banded respectively. Kinglets and Creepers were the dominant species. The return of north winds on the 11th spelled the end of the kinglet and creeper waves. Daily banding totals averaged about 10 birds/day from the 11th-14th. We are definitely in need of a change in the weather as clear skies and north winds have been unrelenting since last weekend.
