Hawk
Cliff Hawkwatch of Port Stanley, Ontario, Canada

September 27
For those that are interested in the Monarch migration ...Not much in the way of passerines reported...but incredibly a strong push of Monarchs today with clusters of 10-11 at a time being seen...despite the SW gales! We've seen this before on rainy, humid days even with strong winds...it doesn't seem to deter the Monarchs.

Weather:

Wow! Gale force wind warnings were up starting after midnight and wind speeds continued to climb throughout the day. Winds were initially very strong from the SSW then gained strength and shifted to SW and eventually WSW. This is the first time I think we've ever recorded multiple hours of >75kph winds...with gusts hitting 100kph. There was a lot of cloud cover and the rain moved in during a couple different hours...but the sky would then break out once more. Temp was much cooler reaching just 15C thanks to the intense low passing eastward with an associated cold front .

For those interested in the Monarchs, today (9/09) was a slow flight day with very few passing the hawkwatch. LOTS of Ruby-throated Hummingbirds today, with 200+ as a rough count during a 9 hour observation period.

September 5
The Monarch butterfly migration was in full swing with several passing the hawkwatch every minute...and at all altitudes from ground level to heights requiring binoculars to spot them.
Observation Start Time: 07:00 End Time: 14:00 Observer Hours: 7
A beautiful day with light NE winds eventually swinging all the way around to SW. Temp still warm to a high of 21C under clear blue skies to start with clouds building in as the day progressed.
