Connecting people with nature in Ontario's Mississippi Valley

Grand Opening of the MVFN Mike McPhail Bird Viewing Shelter

Wednesday, September 5th at 2:30 PM

The Mississippi Valley Field Naturalists (MVFN) are very pleased to announce the grand opening and dedication of the Mike McPhail Bird Viewing Shelter, located just west of Almonte, behind the Municipality of Mississippi Mills Waste Water Treatment plant.

This special project to create a new local birding facility was conceived, developed and built by the MVFN Birding Committee and many other construction-minded MVFN volunteers.  The viewing shelter is dedicated and named for the late Mike McPhail, a former President of MVFN and a tireless advocate for nature in our community.  The Mike McPhail Bird Viewing Shelter is located along the same path as the Al Potvin Observation Tower, which has been well used by birders from near and far for many years and overlooks the largest and westernmost of the decommissioned lagoons.


Bringing a big project from conception to completion involves a lot of planning and many steps.  Starting in the spring of 2017, the investigation of several designs and sizes and shapes of bird viewing shelters was undertaken, and a preliminary structural plan was designed by Michel Gauthier.  This was taken to Mississippi Mills municipal staff for review, and a request to build beside the lagoon on town property.  The project was approved unanimously by Council in the fall, and the necessary building permits were obtained.

A call was sent out to MVFN members for help with construction, and the response was amazing – 22 people signed up!  The first step was to level the ground, and spread gravel, which was done by Howard Robinson and his trusty tractor.  Because of the early onset of winter in mid-November, the cement support posts had to be formed and dried in Al Potvin’s heated garage.  Over the long winter months, volunteers calculated materials needed and arranged to purchase them from Home Hardware in Almonte.

Then the long wait for spring to arrive began, and the crew waited, and waited, then waited some more. Finally, we emerged from early spring to high summer weather, the ground was dry and firm, materials were ordered, and the eager volunteers finally began construction. There were many talented volunteer carpenters and apprentices, which kept the cost down significantly.  However, the “commanders-in-chief” had a knack for organizing work crews on the very hottest days of June!  In spite of the heat, however, the construction moved along quickly, and by early July, the shelter was complete.

And what a beautiful and sturdy shelter it is, with a perfect panoramic view of the lagoon and marsh areas.  Constructed of beautiful pine with a green metal roof, it can be seen off in the distance from Wolf Grove Road. Future plans include permanent signage along the path to the shelter and at the shelter, educational material inside, and natural landscaping around the shelter, which hopefully will attract even more wildlife.

The MVFN Board of Directors and members are delighted with the results of the tireless efforts of the co-managers and construction crews over the past year.  We are proud to offer the public birding community a unique place to visit, spring, summer and fall.  MVFN is also very grateful to the Municipality of Mississippi Mills for allowing the shelter to be built, for the help and support they offered throughout, and to Home Hardware for their expert advice.

Besides migrating waterfowl and shore birds at the lagoon, there are woodland birds along the path, and field birds which can be seen out from each side of the path.  To access the path, turn right off Wolf Grove Road to Concession #8.  The path is located a few hundred meters up Concession #8, across the road from the far end of the Auld Kirk Cemetery.  Parking is permitted on both shoulders of the road, except in front of the gate.  The rather hard-to-see entrance to the pathway is marked with a small yellow sign on the right.  Please respect the “Rules of Etiquette” on the path and in the shelter.

Wild Fluctuations of Bird Numbers at the Almonte Lagoon – Fact or Fake News?

This year again, the Mississippi Valley Field Naturalists, held four bird-watching events at the Almonte Lagoon. The Fall Open Houses, as we call them, took place on consecutive Wednesdays in September at the brand-new Mike McPhail Bird Viewing Shelter. The total number of visitors during the four events topped one hundred.

Enthusiastic birders at the Mike McPhail Bird Viewing Shelter

Before the first event on Sept 5th, we celebrated the official opening of the shelter. After speeches and ribbon cutting, visitors filed into the structure where our volunteers showed many species of birds to anyone interested in looking through one of the available scopes. And so it went for the first two events: people in the shelter, ducks and geese on the water, birds in the sky, and hot weather for all.

To some of the observers, the hot weather of the first two weeks seemed to hinder bird movements. Ducks in particular, did not fly to and fro as much as expected, and numbers appeared to be down.

The third week saw cooler temperatures and the arrival of a large flock of Canada Geese. Now the lagoon was covered with geese and ducks. Thoughts of fewer birds dissipated in the breeze.

During one of the later events, a few conversations turned to climate change and how it could possibly cause wild fluctuations in bird numbers. Were those conversations based on facts or on subjective observations? In the past, we had to rely on personal experience to form a judgment on this, but not anymore.

For the last three years, volunteers from our birding committee have recorded our events’ data into eBird, an online citizen science tool launched in 2002 by Cornell Lab of Ornithology at Cornell University. eBird keeps our data in a central database, available to us at the click of a mouse. Now, we can find out what is really going on with our bird numbers.

Take a look at the following charts. The average number of birds spotted at the Almonte Lagoon during our fall events decreased in 2017 only to bounce back higher this year. On the other hand, the number of species increased in 2017, but decreased this year. So, we end up with a quandary: more birds counted in the years when fewer species are present.

Do those charts show that our bird numbers fluctuate because of climate change? We do not have enough local data to properly answer that question. Some of us wish we did, but we don’t – not yet anyway. Many factors may have skewed this year’s high bird count. For instance, had the large flock of Canada Geese arrived one week later, our average count would be lower. Also, the experience and accuracy of our birdwatchers may have changed over the three-year period. More importantly, the time frame and the sample size of our data are too small.

But what about the hot weather of this year’s first two weeks? Well, some people would say it was just a normal fluctuation. Hum… So many factors to consider…

In any case, our data gathering is a good start. Our checklists now form part of eBird’s database, a database that includes more than twenty million checklists – a huge sample size. It includes historical sightings going back to the days of the passenger pigeon.

Scientists across the globe use this windfall of data to study anything and everything that has to do with birds, including the effects of climate change on bird populations.

Their findings? Yes, climate change has an enormous effect on bird populations. Some species fare better, others worse. Migration patterns change. Ranges expand or contract depending on how well species adapt to change, and according to Nature Canada (How is climate change affecting birds?), extinction risks are on the rise.

But hey, we should remain neutral and not speak about climate change. After all, it’s fake news, right?

Enough said for now. We will revisit the issue next April, after the Spring Morning Walks, yet another yearly MVFN series of bird-watching events.

Until then, hold on to your binoculars.

September Birding Open Houses at the new MVFN Mike McPhail Bird Viewing Shelter

September 5, 12, 19 and 26

NOTE: Link to current E-bird checklist for this location is at

Each autumn, tens of thousands of shore and water birds migrate through our area from their nesting grounds in the Arctic. Hundreds stop off to feed and refuel at the Almonte Lagoons behind the wastewater treatment plant, just west of Almonte.

The Mississippi Valley Field Naturalists (MVFN) have just completed construction of a beautiful new bird viewing shelter overlooking the westernmost decommissioned lagoon. For fifteen years, birders from all over the province and beyond have made this prime location for observing shorebirds and other species one of their important viewing spots. The trail in to the existing Al Potvin Observation Tower now leads on to the new MVFN Mike McPhail Bird Viewing Shelter close to the lagoon. Many fall warbler and sparrow species may also be seen during the short walk in to the new shelter.

On four consecutive Wednesdays, September 5, 12, 19, and 26, MVFN’s Birding Committee invites you to walk in between 3 and 5 PM to view the multitude of shore and water birds from the shelter.  On each of these occasions, you will be greeted at the trailhead by an MVFN member, who will point out directions to the tower and the new shelter. An expert birder with a spotting scope will be at the shelter and will be ready to offer an opportunity to learn the identity of the different birds and tell a bit about them.

Directions: from Almonte, take Wolf Grove Road (County Rd. 16) towards Middleville, 2 km. Turn north onto Ramsay Concession 8 at the Auld Kirk Church and Cemetery, and travel approximately 100 m.  The trail entrance is on the right, across the road from the far end of the cemetery, just beyond the gate. A small yellow sign marks the entrance.  Parking is permitted on both shoulders of the road.

You may visit at any other time on your own.

Help look for loons in the 2018 Mississippi Lake Loon Survey

Here’s a chance to get involved in citizen science while out on the water!

MVFN, in conjunction with the Mississippi Lakes Association, will once again conduct this year’s Canadian Lakes Loon Survey on Mississippi Lake, for Bird Studies Canada.

The task involves pairs of volunteers making one, two or three visits by boat to a section of Mississippi Lake, searching for loons and recording the findings.

The three visits are during the last week of June, July and August. You can volunteer for one, two or all three of the monthly visits. Each visit lasts up to two hours. Maps and forms will be provided.

A motor boat and driver will be made available for each team. Each team will coordinate, with the boat driver, the preferred day, time, and location of the launch.

You will need binoculars and sunscreen.

Orientation session: To prepare for the survey work, an orientation meeting will be held at the Mill of Kintail Gatehouse on Wednesday, May 16 at 1:30 PM. Please register with Cliff Bennett at or 613-798-6295 by May 15.

For further information please contact Cliff.

A Grey and Wet Finale to our Early Morning Birding

A report of the Apr 25, 2018 Early Morning Birding walk, by Tim Pullen 

It was a lowering grey sky that covered us as we gathered at the Carleton Place Arena for our final Early Morning Bird Walk of the season. Thirteen hardy souls gathered together with happy smiles and pleasant chatter as we shook ourselves out into a parade to walk along the Mississippi Riverwalk Trail.

The slow drizzle didn’t dampen our spirits, but it also did not help extend our list of birds. This was really the first April shower day of the year, and the late spring has meant many of our expected birds were missing.

The group was lucky to see one of the earliest female red-winged blackbirds amongst the many busy and noisy males who were starting to stake out territories for the coming season.

We also saw several yellow-rumped warblers flitting through the very tops of the trees over the boardwalk, giving us all a chance to practice our ‘warbler neck’ exercises in preparation for the coming invasion. The bird of the morning was a rusty blackbird. He still had some rusty edges to his feathers, but quickly moved across the swamp and into the trees at the edge of the river. He was a first for this location, but hopefully not the last.

The regular denizens of the forest and open fields were present, robins, nuthatches, chickadees, as well as a few remaining water birds. A pair of swallows, one tree and one barn, gave us a beautiful example of the difference between these two, with the long swallowtail of the barn swallow clearly marking the difference.

The drizzle never really stopped, but we did manage to record 26 different species, and when you look at the list you will see the mix of birds that make this such a good location for birding, with the different habitats all nicely joined by a good trail. It was a wet walk but enjoyed by all.
