Visitors:
Lots of visitors today including folks from the K-W Birding club and the
University of Guelph. I'm glad that our expectation of a good Peregrine
flight came to fruition! A big thanks to Tom B, Mac M, Ronnie G, Su R and
Ken W for helping with spotting and ID'ing the birds for everyone and
getting the count done for today.
Weather:
Well the forecasters got the winds correct as we saw strong SSW and SW
winds for the day right up the cliff. Luckily the rain associated with the
passing cold front stayed far to the north but also provided lots of cloud
cover for the day before mostly clearing out as the front passed. Temps
started at 14C and got to a high of 23C.
Raptor Observations:
The bulk of today's flight of 424 birds were TVs (358). However, as
predicted on the strong SW winds the highlight today was the Peregrine
flight with a total of 29 of these speedsters. This is definitely one of
the better one day flights for this species in a while. It's great that
these birds showed up today for the many visitors that were down to the
site!
Non-raptor Observations:
Non-raptors were not reported for today. Check out the number of eBird
checklists submitted for the Hawk Cliff hotspot today to see what
non-raptors were around.
Predictions:
The next 2 days (Monday and Tuesday) are looking promising for raptor
migration with winds forecast to be moderate to strong from the NW both
days across the entire southern Ontario region along with a mix of sun and
cloud. This should push migrant raptors down towards Lake Ontario and Lake
Erie and the hawk watch sites along their shorelines. Typically, the 2nd
day of NW winds (in this case Tuesday) will often have a larger flight.
The TUV (thermal updraft velocities) are also supposed to be pretty good
both days but especially on Monday with a TUV forecast of up to 500
ft/min... which basically means if thermals do form the birds will be able
to get a very nice lift as they soar.
