Marlborough Forest: Summer 2022

Eastern Comma

I did not get out to Marlborough Forest as often as I would have liked this past summer; ongoing medical issues early in the season left me feeling too tired and too sore for the long five-hour outings I enjoyed so much last year. On June 2nd I visited the E6 trail with Rick Collins to look for the Sedge Wrens breeding there. We heard one without too much difficulty, though we weren’t able to spot it. Our other highlight was a female Ruffed Grouse on the trail trying to lure us away from its chicks (none seen) by giving distress calls. It was a gray, drizzly day so I didn’t see any insects worth photographing. Indeed, I didn’t take my camera out of my bag at all.

The weather was much better on June 19th, so Chris Traynor and I went to trail E4 to look for Twin-spotted Spiketails and some different emerald species for his life list. I was also eager to how him the pool below the culvert as this was where I’d seen my one and only Ocellated Emerald hanging out in 2020. It was a bit windy, but the sun was shining and the weather was warm, and the breeze made the usual biting insects less of a distraction.

Ode-hunting along the River

Shadow Darner

Mud Lake and Andrew Haydon Park are usually excellent places to find different species of dragons and damsels throughout the summer months. In both 2015 and 2019 I had a good number of species at Andrew Haydon Park in late July, and an OFNC dragonfly outing at Mud Lake on July 21, 2013 also netted some fantastic species. I was hoping for some similar luck on an ode-hunting trip on July 24th, but this time I found fewer species and fewer individuals overall. I am not sure why there seem to be so few dragonflies around good pond habitat these past two years (such as the Eagleson ponds), but the trend is concerning.

My first stop was the shoreline at Mud Lake where I hoped to find some large river clubtails perching on the rocks in the channel behind the filtration plant. When I arrived I was happy to find two dragonflies perching on the rocks right away, and managed only to photograph one before a couple of people came along and scared them both – while I’m certain one of them was a clubtail, the one I photographed turned out o be an Eastern Pondhawk. The clubtail did not return, although I saw a couple flying out over the water several times on my visit.

Searching for Skippers at South March Highlands

Little Glassywing

Last year I discovered that the South March Highlands was a great spot to see some of the more uncommon sedge skippers in our region; I have been waiting all summer for July to arrive as I couldn’t wait to return this year! Last year I got my lifer Little Glassywing on July 5th and my lifer Mulberry Wing on July 12th, so I had high hopes for this visit on July 2nd. Though a few days earlier than my visits last year, members of the Ottawa butterfly group had already started reporting sedge skippers elsewhere, and so I was eager to check this under-reported area for the ones I had seen last year. The milkweed patch also hosts hairstreaks, fritillaries, monarchs, sulphurs and many other insect species – I thought for sure I would find something interesting on my visit!

A trip to Morris Island with the McNamara Field Naturalists

Slaty Skimmer

On Saturday, July 3rd I accompanied the McNamara Field Naturalists on their first in-person outing since the latest Stay-at-Home Order ended on June 2nd. Ontario entered Stage 2 of its reopening plan on July 2nd, which raised the number of people who could attend outdoor social gatherings and organized public events to 25 people (as well as allowing haircuts and personal care services again). Although I am not a member of the McNamara Field Naturalists Club, which calls Arnprior home but whose explorations include a large swath of the Ottawa Valley, one of my friends happens to be in charge of putting field trips together, and asked if I wanted to help lead a dragonfly walk. I said yes, and suggested Morris Island as it’s a great place to find all sorts of odes, including several flashy skimmers and clubtails that can be found perching in the vegetation and along the trails. I was thrilled when my mentor Chris Lewis joined us, as it would be easier to find some more of the unique species with a couple of knowledgeable people looking.

Dragon-hunting in the Carp Hills

Great-spangled Fritillary

On June 20, 2021 I accompanied fellow OFNC members Derek and Erik to the Carp Barrens Trail off of Thomas Dolan Parkway to assist them in a survey of breeding birds and other wildlife. Because of the sensitivity of the ecosystem and number of at-risk species which breed here, this trail is closed to the public during the summer. In order for us to access the site, Derek had acquired a permit to allow us to look for unique breeding birds such as Black-billed Cuckoo, Eastern Towhee, Common Nighthawks and Whippoorwills. Derek and Erik started around dawn to listen for both nightjars, but heard none. I joined them at 6:00 am while they were still walking along Thomas Dolan Parkway, and together we entered the trail system.

The trail follows a rocky outcrop around a long slough. Many birds were already singing, and we heard the typical open field and woodland edge species: Field Sparrow, White-throated Sparrow, Veery, Scarlet Tanager, Rose-breasted Grosbeak, and many warblers, the best of which (in my humble opinion) included two Pine Warblers, two Yellow-rumped and two Nashville Warblers.

Dragonfly Emergence

My first real dragonfly outing of the year occurred on May 24, 2021, and as usual, took place at Roger’s Pond in Marlborough Forest. I invited a few friends to join me now that outdoor gatherings can include up to 5 people, and fellow OFNC members Derek and Gerald decided to join me. It was a warm, sunny day, and I hoped to find the usual common skimmers and clubtails, as well as a few uncommon species that I’d seen previously at Marlborough Forest such as the elusive Ebony Boghaunter and Harlequin Darner. I’ve already seen one boghaunter this season, but it’s been a few years since I’ve seen a Harlequin Darner, and the Cedar Grove Nature Trail has been a repeat site for this ode.

We met at 9:30 am, just early enough to get some birding in while waiting for the sun to rise higher in the sky. We had the usual Nashville Warblers, Black-throated Green Warblers, Great Crested Flycatchers, White-throated Sparrows, Veeries, and Yellow-bellied Sapsuckers on the walk in. At the pond itself we had Eastern Kingbirds, a Pied-billed Grebe, Common Yellowthroats and four Ring-necked Ducks. Many dragonflies were already flying along the open trail through the cedar forest, including a few teneral whitefaces and emeralds.

South March Butterflies

Little Glassywing

On July 5th I headed over to the South March Highlands to check the open milkweed field at the Klondike entrance for butterflies. It was a little earlier than my visit last year when I added the Striped Hairstreak to my life list on July 13th, but after having seen a Banded Hairstreak at the Rideau Trail yesterday, I figured the large milkweed patch might hold a few surprises.

I arrived at 10:00 am, and it was already heating up a tad uncomfortably – the daily high temperature hasn’t dipped below 30°C this month so far, and the forecast called for another 30°C high today. It’s great weather for looking for bugs, although they, too, retreat to the shade during the hottest part of the day when the temperature becomes unbearable.

Dragonflies and Butterflies at Mud Lake

Long Dash Skipper

Once migration winds down, many birders stop visiting Mud Lake while they look for breeding birds elsewhere. Although birds such as Wood Duck, American Redstart, Yellow Warbler and Common Ravens are abundant and easy to find at the city’s premier migration hotspot during the breeding season, many of Ottawa’s summer specialties – such as Grasshopper Sparrow, Lincoln’s Sparrow, Golden-winged Warbler, Mourning Warbler, and Sedge Wren – are found elsewhere, and so most birders switch their focus from looking for migrating transients to chasing these summer residents down just as soon as the last Blackpoll Warblers and Arctic Terns disappear in early June. This is about the same time my attention to dragonflies and butterflies intensifies – and Mud Lake is a great place to find a good variety of both these insects.

Adventure in Dunrobin

Snowshoe Hare

On June 5th I headed out to Dunrobin to spend some time looking for odes and birds. My first stop was the Crazy Horse Trail on March Road at the end of Huntmar Road. This is a relatively new pedestrian-only trail for hikers, skiers, and snowshoers that was developed by the Friends of the Carp Hills under an agreement with the City of Ottawa. It is named for an old tavern that used to stand adjacent to the trailhead but has long since been demolished. The goal of the trail is to provide recreational access to the the Carp Hills on City-owned property while keeping impact on the environment to a minimum. The trail is narrow, and as there is no intention to groom or widen the trail, people are asked to respect the natural areas by staying on the trail, keeping dogs under control at all times (which means using a leash if necessary), leaving no waste, and respecting property boundaries. There are some rough, volunteer-built boardwalks in places too wet to cross which adds to its charm. In fact, all trail maintenance and improvement depends on volunteers, rather than the City, which makes it doubly important to respect the work they have done in creating this trail.

The South March Highlands Project

Striped Hairstreak

After my visit to the South March Highlands on June 16, 2019, as I started logging all my photos into iNaturalist I thought how great it would be if there was a citizen scientist project that documented all the flora and fauna of the South March Highlands. This is an area that has already lost precious wetlands and old-growth habitat to developers, and still continues to be threatened today. As a few limited studies have already identified a number of species at risk within the South March Highlands, I was surprised to see that no one had created a project on iNaturalist – one of the easiest ways to document the flora and fauna living within a defined area.

iNaturalist is to plants and wildlife what eBird is to birds – a collective database that anyone can contribute to. And while the observations entered into iNaturalist depend heavily on photos submitted, the beauty of setting up a project is that it will automatically collect all the observations from the geographical area defined by the creator, subject to the parameters of the project – there are general species projects for geographical areas (such as Mud Lake and Gatineau Park), projects for specific types of wildlife (such as the Lady Beetles of Ontario or the CWF’s Help the Turtles project), and specialty projects dedicated to certain types of behavior (such as my personal favourite, Odonates Eating). It doesn’t take long to create a project – the most time-consuming part for me is defining the boundaries on the map. So during the next few days I spent some time tinkering with the iNaturalist website, and thus the South March Highlands Species Project was born.
