February 20 [Day 5] (Valley View site) The weather for most of the day was a rerun of that of yesterday with the temperature reaching -2C from a morning low of -7C, with ground winds generally light SW but occasionally reaching 16 km/h and moderate NNE upper winds. Light and occasionally moderate snow persisted until 1620 with the ridges partially obscured, with 90-100% stratocumulus and cumulus cloud cover to 1530 after which the cloud dissipated to 0% after 1700 which allowed the temperature to fall to -8C by 1800. The only raptor seen was a non-migratory Prairie Falcon at 1606 which was the first for the season [bird species #20], and Black-billed Magpie [#19] and a singing female Great Horned Owl [#21] at 1741 were also seasonal firsts. Early courtship food begging by a female Grey Jay from a male was observed at 0835, and a Barred Owl sang once at 1615. The weather now appears to be set fair for a number of days so we should finally start to see some more concerted raptor movement after what has been a slow start. 11 hours (53.34) No migrant raptors (8)
