Today, as we said our thankyous and
goodbyes to Richard Welsman, the ‘retiring’ gardener at Rosetta, we brought to an
end the 2017 Raptor Watch at RMG.
The collective, better known as ‘The Friends of Rosetta’ did a fabulous job this fall with the Watch. I’m sure that not very many hawks got by without being noticed, photographed, identified, and counted. Having said that, unfortunately this was not the migration season we’d all hoped for. Numbers were way down on many of our favourites. This of course, does not mean in any way that the birds are in-decline, it just means that the conditions were not right for them to be blown down to the shores of Lake Ontario and then eventually bringing them over the park. A huge lack of northwest wind during peak times of the migration was the culprit. Not every year is going to be bigger and better than the last and this was one of them for sure. We certainly enjoyed every bird that did see all the same and, we had at least one of each species to keep things exciting. Thankyou everyone!
The following is a review of what happened during our time at the Watch this fall and all stats are based on our 14 year study of migration at Rosetta...
Total Raptors (4265) - Our 11th best year ever at Rosetta McClain Gardens. We had 6 count days with over 100 birds, 2 with over 500 birds, and 1 with over 1000 birds. Our highest day count for the season occurred on October 16th when we observed 1407 birds. Unfortunately, no records were broken this year. Our last day of raptor migration counting occurred on November 29th.
Turkey Vulture (2680) - Our 3rd best year ever for this species. October was our 5th best month ever for 'TVs' with a count of 1831 birds. Our highest day count for the season occurred on October 16th when we observed 1128 birds. Our last Turkey Vulture of the season was observed on November 27th.
Osprey (34) - Our 14th best year ever for this species. Our highest day count for the season occurred on September 8th when we observed 11 birds. As the case in previous low count years - with all the hot humid low to no wind days that occurred during the first half of the fall season, it's likely that many Osprey migrated across the city further to the north and out of our viewing range. Our last Osprey of the season was observed on October 16th.
Bald Eagle (73) - Tied for our 4th best year ever for this species. September was our 6th best month ever for 'baldies' with a count of 38 birds. Our highest day count for the season occurred on September 28th when we observed 13 birds. Our last Bald Eagle of the season was observed on November 7th.
Northern Harrier (103) - Our 12th best year ever for this species. Our highest day count for the season occurred on October 16th when we observed 14 birds. As the case in previous low count years - with all the hot humid low to no wind days that occurred during the first half of the season, it's likely that many Harriers migrated across the city further to the north and out of our viewing range. Our last Northern Harrier of the season was observed on November 19th.
Sharp-shinned Hawk (634) - Without a doubt our 14th best count ever for this species - only 3079 birds shy of a new record - OMG!!! Interestingly, our highest two-week count of 'sharpies' for the season occurred during the last half of October when we tallied 250 birds. Our highest day count for the season occurred on October 16th when we observed 152 birds. As the case in previous years and as with other species, the hot humid low to no wind days that occurred during the first half of the season likely caused many 'sharpies' to migrate across the city further to the north and out of our viewing range. Our last Sharp-shinned Hawk of the season was observed on November 29th.
Cooper's Hawk (44) - Our 14th best count ever for this species. Our highest day count for the season occurred on September 8th when we observed 6 birds. Our last Cooper’s Hawk of the season was observed on November 22nd.
Northern Goshawk (2) - Our 14th best count ever for this species - only 27 birds shy of breaking last year’s RMGRW record of 28 birds….wait, what?!?! Our highest day count for the season occurred on November 10th and 13th when we observed 1 bird on each. Our last Northern Goshawk of the season was observed on November 13th.
Red-shouldered Hawk (23) - Our 8th best year ever for this species. Our highest day count for the season occurred on November 10th when we observed 7 birds. Our last Red-shouldered Hawk of the season was observed on November 27th.
Broad-winged Hawk (60) - Our 11th best year ever for this species. Our highest day count for the season occurred on September 28th when we observed 26 birds. Again, this species, as with so many others was likely moving across the city further to the north and out of our viewing range during all the hot humid days of September. Our last Broad-winged Hawk of the season was observed on October 16th.
Red-tailed Hawk (286) - Our 13th best year ever for this species - missing the RMGRW record by just 734 birds! Our highest day count for the season occurred on October 16th when we observed 60 birds - amazingly, we didn't have a single day this fall with a count of over 100 birds. Our last Red-tailed Hawk of the season was observed on November 29th.
Rough-legged Hawk (4) - Our 11th best year ever for this species. Our highest day count for the season occurred on October 26th when we observed 2 birds. Our last Rough-legged Hawk of the season was observed on November 6th.
Golden Eagle (7) - Tied for our 8th best year ever for this species. Our highest day count for the season occurred on November 10th when we observed 3 birds. Our last Golden Eagle of the season was observed on November 10th.
American Kestrel (223) - Our 13th best year ever for this species. Our highest day count for the season occurred on September 28th when we observed 119 birds. Another species that likely migrated across the city further to the north and out of our viewing range during the hot humid days of September. Our last American Kestrel of the season was observed on October 26th.
Merlin (33) - Our 12th best year ever for this species. Our highest day count for the season occurred on October 30th when we observed 8 birds. Our last Merlin of the season was observed on November 27th.
Peregrine Falcon (30) - Our 14th best year ever for this species. Our highest day count for the season occurred on September 28th when we observed 5 birds. Our last Peregrine Falcon of the season was observed on November 6th.

Unidentified Species (29) - Although a little hesitant after so many years to finally include the 'unidentifieds' in our count for the 2017 migration, I’m now very happy that we did. It shows that we’re not perfect and that we do get raptors we just cannot identify to species. In the end, it added a much-needed 29 birds to our count. In previous years these birds were just left off the sheets.
Plus...
Species Survey - Birds (132) - Highlights included the following new species for our 'Park List' - Northern Waterthrush. Our list of bird species identified at Rosetta since 2001 officially now sits at 212 species! Other great sightings included; Short-eared Owl (observed on two different occasions), Olive-sided Flycatcher (observed over several days), and two not identified to species; Ross’s/Ross’s hybrid Goose (yes it’s over, no further discussion please), and Teal duck (either Green-winged or Blue-winged). Every fall we always manage to find some fantastic birds passing by/through the park! Great work everyone!
Species Survey - Mammals (9) - Very limited sightings of the fox(es) was a highlight. Also, today I was informed that a Coyote was seen in the park back in September.
Species Survey – Butterflies and Moths (28) - It was another excellent season, in fact a record season for butterflies due in part to all those hot humid low to no wind days in August and September. One new species was observed, a Dun Skipper on September 26th - a little triangular-shaped guy that is all brown in colour. Other great sightings included; Pipevine Swallowtail, Giant Swallowtail (many), Spicebush Swallowtail, American Snout, White Admiral, Red-spotted Purple, and Common Buckeye. Of interest, The Fiery Skipper which we observed in the gardens for nearly 3 months straight last fall, was almost non-existent this year. Both the Monarch and the Painted Lady butterflies were observed in amazing numbers at Rosetta. On October 10th there was an estimated count of 7500 Monarchs flying by the Watch! That alone is 3000 more Monarchs than our count for the entire migration last fall! Unfortunately, a complete migration count was not conducted this season but numbers overall were extremely promising for this now ‘endangered’ species.
In mid-August, a ‘provincially’ rare moth, called a Fadus Sphinx, was observed and photographed in the main garden area. This drew many of Toronto’s finest moth and butterfly experts out the following Saturday morning in hopes of finding this extremely rare visitor. And, although not seen again, the sheer number of searchers that day left us with our best single-day count ever for butterflies with 21 species being tallied. The very beautiful Hummingbird Clearwing Moth was observed on multiple days in August and September. To finish off the season - on the final few days of the Raptor Watch in November a small number of Fall Cankerworm moths were observed.
Monarch Butterfly Tagging (1487) - Terry and Betty, with the help of many others, managed to capture, weigh, measure, tag, and release an incredible 1487 Monarchs this season! They could've easily doubled that number! So far, this year's ‘Rosetta tagged’ Monarchs have only been found and photographed in one location – Acambaro, Mexico! The city is less than 100kms from the Monarch Butterfly Biosphere Reserve where they normally spend their winters! It took this little butterfly (tagged ‘XAL289’) only 61 days to travel from Rosetta McClain Gardens to Acambaro, a journey of close to 4000kms. If that’s not incredible enough, from all counts this was the first sighting in Mexico of any ‘2017 tagged’ Monarch from across the entire United States and Canada! This was big news for the people of Mexico and stories of the find were printed in many of the newspapers there. We now wait to see how many more of Terry and Betty's Monarchs are found in Mexico at the Reserve during the spring of 2018.
Thank you everyone!

Fantastic recap of the year Walter, Sometimes its not about the count but just being outside and enjoying whatever the day brings. The Rosetta McClain raptor watch is by far the friendliest I have attended and proud to call many of you as friends. With so many experts coming to the watch either daily or regularly tells you that along with the great location its the people that come out that makes the difference.
Thanks for the comment Arvo.
Each fall it always amazes me who comes out to attend our Raptor Watch and the park in general in search of birds. So many faces - some new to birding, some new to hawk-watching, some from other raptor watches, of course - all the core group, and also those who just stop-by, if only briefly and out of curiosity, and see at least a bird or two. The Raptor Watch at Rosetta McClain Gardens would not be possible without every single person's contribution no matter how great or small each fall. As you mentioned, the conversation and camaraderie at our Watch is second to none for sure. Who will soon forget me dumping the contents of my yogurt container down the front of my jacket while trying to look at a nearby butterfly with my binoculars - LOL!!!
If I can speak for Terry and Betty, I'm sure that they both feel the same when it comes to their Monarch Tagging program in the Gardens as well.
