2010 Fall Bird Count

Hamilton Fall Bird Count 2010

HFBC Results

by Bill Lamond

The 2010 Hamilton Fall Bird Count (HFBC) on 7 November produced at total of 126
species. This is the lowest total since 2000 when 125 species were recorded. The results were disappointing as expectations were high that some northern species might be recorded. I was expecting for someone to find a Boreal Chickadee as there
was a modest invasion into southern Ontario this fall. Moreover, I was more
intrigued by the possibility of a Gray Jay, another species that is on the move southwards. However, neither of these species was noted. I was also expecting a fairly high species total in the range of 140+ species as there had not been any intense cold weather to push lingering birds out. So the results to me were quite a disappointment. It seemed that a lot of birds must have cleared out in the week before the count. Having the count on the last day possible in the count window (November 7th) did not help either. I think most observers were disappointed in their totals. These are some sample comments:

“Needless to say it was a poor count as most birds had migrated”;

“It was a pretty dull count with nothing too noteworthy, probably my lowest species total for the area”;

“A very disappointing count this year. Some areas that normally produce were
devoid of birds”;

“Bird numbers were down significantly this year”;

“A very slow day”;

“The weather was good and we expected good numbers. However, the birds must
have found something better to do than hang around waiting for us to count them.
We spent the day wondering where they were”;

“After 4 hours of very frustrating searching I came up with very few birds…it was almost scary!!!”;

“Pretty sad numbers. Birds tended to be fewer this year than last”; and
“Worst in years”.

Ok, ok enough, we get the picture. However, not everyone was as pessimistic about
the count. I found my area in Brantford to be about as “birdy” as it usually is
and another nearby observer stated “it was an excellent day”. Mind you, he saw a Golden Eagle.

There were some significant highlights on the count. There were two new species for the HFBC in 2010. Most significantly a Le Conte’s Sparrow was seen in the Clappison’s
Corners Wetland behind the Rona store in southwest Waterdown. This bird was
originally found by Tom Thomas on the previous Thursday (Nov 4) and was seen on
count day by Owen Novoselac and many others. This was only the 7th record ever for
Le Conte’s Sparrow for the Hamilton Study Area (HSA). The other new count bird was
a first winter Thayer’s Gull at the Stoney Creek lakeshore at Grays Road seen by Bill
Smith, Alf Senior and Peter McParland.

There were a few other highlights to report as well. The count’s second ever Pine
Warbler was observed by Jacob Bruxer, Tom Crooks, Dave Don, and Tom Ford along
a hydro right-of-way between 1st and 2nd Concession northeast of Hagersville. A
Purple Sandpiper was observed on the rocks at Fifty Point C.A. by Andrew Keaveney. This was only the 3rd record for the HFBC. There were some high counts that are
worth noting here. The seven Tufted Titmice bested the previous high by one bird.
Red-bellied Woodpeckers continue to increase with a 7% increase over last year’s previous record. Of course the distribution of this woodpecker is uneven in the HSA, but it is more common than Hairy Woodpecker in most of our birding circle. Also of note was a record-high count of seven Northern Saw-whet Owls. This is just a chance occurrence, most likely due to dedicated birders looking for roosting birds in suitable habitat. Sandhill Crane numbers reached an all-time high with 30 individuals in the HSA on count day. This species is definitely on the increase. Both Golden and Bald Eagle totals were record-high. The five Golden Eagles, although certainly noteworthy, is really no surprise. Numbers of fall migrant Golden Eagles through Ontario have been exploding in the past two decades. This year alone, as of Nov. 11, there have been 141 Golden Eagles reported at Hawk Cliff with an amazing 40 individuals observed on the first day of November! Likely, a good percentage of these birds migrate through the HSA. Likewise the seven Bald Eagles on the count is no surprise to me. This species’ population continues to increase throughout Ontario and it is increasing in the HSA as a migrant, as a breeder and as a wintering bird.

Speaking of eagles, it was a bit of a challenge to try to accurately record the
number of both Bald and Golden Eagles in the HSA on count day. If I just recorded
all eagles without any scrutiny, there would have been eight Golden Eagles and 15 Bald Eagles. Eagles are large, conspicuous, sought-after birds which are prone to be re-counted as they move across territory boundaries. There were three juvenile Golden Eagles over Joe Sam’s Park in Waterdown between 9:45-10:15am. Based on discussions with observers, one of these birds was seen later over the Rona store in Waterdown and two of them were seen over Ancaster Creek in Dundas based on timing. Another Golden Eagle was seen over the Dundas Valley along Martin’s Road
but was determined to be a separate bird as it had a distinctive trailing flight
feather and it was seen at 11:30am. The other Golden Eagle in north Brantford may have been one of the Dundas-Waterdown birds but it is likely a different bird and
has been recorded as such. With the Bald Eagles it was more difficult to determine
actual numbers. There were four adults along the Grand River in the Brantford area but conservatively, I have left it as two to correspond with the pair that nested there. In the Hamilton Harbour-Cootes Paradise area, 11 Bald Eagles were reported by four adjacent parties. However, careful attention to plumage differences, timing of observations and discussions with the four parties, pared this group down to five birds.

The 2010 HFBC had six “Significant Species”. I have outlined in the past the definition of a “Significant Species” which is a species that has been seen on 20% of counts or less. With this being the 37th count, species seen on seven or fewer counts are considered significant. The number of “Significant Species” can be a measure of how “good” the count is. This year with six “Significant Species”, the same total as last year, but well below the record total of 14 in 1975, the count is about average in this respect. The other “Significant Species” seen this year are Great Egret (6th count record) and Common Raven (7th count record). Both of these species will undoubtedly come off of this list in a few years as Common Raven has now been recorded for seven consecutive years now that it is a HSA breeding species. Also, the Great Egret is being recorded more frequently now (six years since 1992) and it will soon come off.

Also of note this year was the recording of six finch species including White-winged
Crossbill and Evening Grosbeak. Evening Grosbeak has really declined across Ontario
and this is only the second record of this species on the HFBC in the last nine years.

There were lots of negatives on this year’s count. Topping this list is the paltry number of shorebirds. Only five species were recorded, an all-time low. There have been four other years with only six species. Additionally, only 112 individual shorebirds were counted. Both woodcock and snipe were missed for only the 3rd time each and Pectoral Sandpiper was missed once again. This is becoming a familiar pattern with shorebirds on the fall count. The numbers of almost all species keep on dropping due to actual declining populations and/or decreasing habitat in the HSA. The number of Great Black-backed Gulls on fall counts continues to decline. Back in the early-90s, the average count for this species on the HFBC was around 190. Since that time numbers have gradually decreased such that a low water mark was reached this year with only 10 birds. However, this species population in North America is apparently stable and the reduction on the fall count seems an anomaly. Potentially this species is just migrating into our area later and later each year from the east coast, possibly due to warmer fall temperatures. The Hamilton CBC numbers do not show this same declining trend. One other negative seems to explain a lot about the 2010 count, at least to me. I have heard someone in the past say that a good indicator of lingering insectivorous birds is the Ruby-crowned Kinglet. The story goes that if you have lots of Ruby-crowned Kinglets on your count, it is a good sign that there will be lingering swallows, vireos, warblers, phoebes, gnatcatchers, etc. This year we had none of the aforementioned species save for the usual Yellow-rumped Warblers and the exceptional Pine Warbler. On this year’s count we had only six Ruby-crowned Kinglets, a record-low total. Maybe there’s something to this.

So all in all, pretty much an average count with the species total of 126 being below the all-time count average of 130. Some were expecting more but it is noteworthy that we added two new species to the count in its 37th year. It is also worth noting that for the first time we had over 140 observers on the count. The HFBC just keeps getting more popular which is a very good thing. I want to thank everyone for getting their results to me so quickly and concisely and for promptly answering any questions that I had. I hope to see all of you back next year.
