Point counting begins in Frontenac Park


The Point Count is a standard method for gathering data on the relative abundance of breeding birds. This method typically involves a 3, 5 or 10 minute count of all birds detected from a fixed position and is conducted year-after-year from the exact same spot. Annual replicates of point count surveys enable the calculation of population trends and can also infer correlations of temporal changes in relative abundance to specific habitats and many other parameters dictated by survey design. For the Frontenac Breeding Birds project, we will be completing 80 off-road point count stations within Frontenac Provincial Park as well as 120 roadside counts along secondary and tertiary road systems in the study area. This is a big undertaking but will provide a sound baseline assessment of the avian communities in the area. At least for now our point counts will be focused on terrestrial habitats, primarily of the forested kind.

I emerged from the house at dawn on June 8th to begin the first morning of point counts in mature deciduous forest habitat in the park. I heard a Winter Wren singing mightily from the opposite shore of our dock and wondered if I might have a chance to investigate later in the day after the surveys were done. I was about to enter some of the oldest forests in the region and didn’t have any time for dawdling so I carried on to the first station after a short boat trip across Kingsford Lake.


These forests are quite diverse with tree species but the main representatives are Red and White Oak, White Ash and Sugar Maple. The light diffusing through the canopy was quite spectacular and I was pleased to write down a singing male Cerulean Warbler at MH1, the first station of the day! Ceruleans are quintessential canopy dwellers, rarely descending to heights that would afford even a decent glimpse, although they do occur in less mature forests at Queen’s Biological Station.


This is one of the grandparent trees in the forest, easily a century old White Ash that pierced through the upper canopy. My jets hat was used to give a better sense of scale of this monster!


This is a view straight up to the canopy along the trunk of the ash and the Ceruleans like to hang out up near the top somewhere. Fortunately, I’ve been finding that their buzzy songs carry a decent distance through the forest and they are frequent songsters, even well into mid-afternoon.


This particular point count route was about 4 kilometres long in total with twelve stations spaced evenly by 330 metres. The route carried me nearly the full length of Kingsford Lake to the north end of the park and Devil Lake. There was much more than just birds to look at during the trip including this abandoned mica mine, which was established in 1844 and terminated in 1949. The mine shaft was fenced off and all that remained of the operation were piles of mica shards and a heap of old equipment and furniture as seen in the photo below.  Mica is abundant in the area, glowing in the soil and exposed rock on sunny days.



The undulating landscape of ridges and valleys is a hallmark of the Frontenac Arch where the Canadian Shield rears up dramatically at its furthest position south. The valleys often contain ephemeral pools and wetlands, which create ideal growing conditions for these ferns that were over a metre and a half tall. Northern Waterthrushes thrive in these areas of the park.


Back to the birds. After completing the first route through mature forest on the 8th, today I finished up the first of three routes to be conducted in younger hardwood forest of the park. An obvious highlight of the two survey routes was the abundance of Cerulean Warblers detected. This little wet clearing in a relatively young hardwood stand contained three males that sang from the confines of their respective territories at the edge of the clearing.


This is a photo of one of my survey forms from this morning, which records no less than three counter-singing Cerulean Warblers! The inner circle has a 50 metre radius and the outer extends from 50-75 metres. This grid is used to keep track of who is where while you are working as it can become quite confusing when there are a lot of birds in your immediate area. The hashmarked lines connecting CERW and SOSP indicate countersinging birds, which helps to confirm that individuals aren’t being double-counted. Birds with small dots were detected in the first three minutes and those with stars and triangles were recorded between 3-5 and 5-10 respectively. There were twelve species within 75 metres at this particular station, including a Yellow-billed Cuckoo (YBCU) and a Scarlet Tanager (SCTA) among the Ceruleans (CERW), American Redstarts (AMRE) and Red-eyed Vireos (REVI). Also present were Northern Flicker (NOFL), American Robin (AMRO), Song Sparrow (SOSP), Great Crested Flycatcher (GCFL), Chipping Sparrow (CHSP) and White-breasted Nuthatch (WBNU).

The first day of point counts finished off nicely with a Louisiana Waterthrush near Crab Lake at the last count and in the last minute! In all a total of 14 Cerulean Warblers were detected along the route through mature deciduous forest. Another 15 were recorded this morning in younger hardwood forests near Birch Lake to the south of Kingsford for a total of 29 singing males in two mornings of point count surveys in Frontenac Provincial Park! The 24 surveys completed so far are at best a slice of what is there and I still have two more routes of twelve counts each in the younger hardwood forests.


Lastly, after walking back the four kilometres from Crab Lake on Monday, I checked in on that singing Winter Wren I’d heard singing about seven hours before. After about 60 minutes of quietly watching the male and female in their territory, I was able to locate their nest underneath this mossy old stump. It was pitch black under there and I had to basically lie down in the swamp with my flashlight and pocket mirror to find what is effectively a hidden hole in the ceiling of the stump about the size of a two dollar coin! The nest contains three very small chicks and with any luck you will notice the tips of their bills in the photo below.

  1. Oh my. Gorgeous habitat. How do you keep on schedule with so many beauties to distract you? Speaking of schedule, how long will you be maintaining your demanding point count discipline?

    Warm regards to that white ash next time around!
