About Banding
October 18 2003
This update on migration monitoring results encompasses the period of
October 9th-18th.

723 birds were banded for the 10 day update period at a rate of 72
birds/day which is consistent with the average for the previous update

Recent highlights include: Lapland Longspur (observed on the 19th),5
Pectoral Sandpiper and 1 Northern Goshawk (obs. 14th of October)and
increased numbers of Slate-coloured Junco, White-throated, Fox,
Swamp, Song and White-crowned Sparrows. The first American Tree
Sparrow was observed this morning.

There has been much speculation over the weather events contributing to
migrant "fallout
s" at Tommy Thompson Park. The past two nights have
been nearly identical in terms of cloud cover and temperature. 55
birds were banded yesterday and 138 were banded today. Future
analysis of weather data with census and banding totals will be
