2010 banding statistics

Outdoor activities are curtailed while snow and ice is on the ground. Hence I turn to compiling banding statistics.

The data covers too few years to uncover trends. I have noticed a change in presence/absence of several species but data for additional years is required. Then I'll also consult other data sets before reaching any inferences.

I am pleased with the variety of species banded. This station is located in a rural/suburban landscape mix. Planning authorities are approving smaller lot developments. The proportion of woodland and woodlot size is likely to diminish within a one mile radius of the station.

This year I banded more during migration. The species caught on a Friday differed from those the following Monday. This is probably an example of how species move in groups or waves. I'll look for more evidence of this.

Individual birds from both neotropical and wintering species have returned in subsequent years to this locale. None of the birds banded here have been reported as found elsewhere and I have not found a foreign recapture so information is not available on where birds may be at other times of year.

I'll continue to band whenever possible during the winter months so that data is accumulated on wintering populations. As weather patterns change, the composition of these wintering flocks may alter.

STATION 2007-2010 (3 ½ years, includes MAPS data)

Number of species recaptured: 14

2010
2010 YEAR (includes MAPS data)
