Connecting people with nature in Ontario's Mississippi Valley

 August 19, 2016

The Almonte Lagoon and Nature trail, across from Auld Kirk cemetery on Ramsay Concession 8, has been the recipient of several rare birds over the past few years. The Mississippi Valley Field Naturalists (MVFN) Potvin Observation Tower provides  views across the lagoons.

On Saturday morning, August 13th, a Western bird, a juvenile male yellow-headed blackbird was spotted by noted Ottawa birder Mark Gawn, feeding on the exposed mudflats and hiding in the cattails. Immediately the signal went out over the birding networks and area birders began pouring in to get a glimpse of this rarity. At one point in the morning, a peregrine falcon zoomed in over the lagoon like a marauding spitfire and scared all of the shorebirds and the blackbird away, but within half an hour, the rare visitor returned, much to the delight of those who came to observe the bird and log the sighting in their records.

The yellow-headed blackbird has a range across the west from Lake Michigan, with a few coming into the Point Pelee area around Windsor. An inch larger than our most familiar red-winged blackbird, the adult male is all black with a brilliant yellow head and chest. Most distinctive is a white wing patch. The adult female has a more mottled yellow head and chest and does not show a wing patch.

The Almonte lagoon and Nature Trail sports an observation tower overlooking the fence and berm. The tower, named for its donor Al Potvin, was erected by MVFN several years ago and the nature trail leading to the tower is maintained regularly by MVFN members.

Having this excellent site and access trail in our area is of great value to local birders and others, and also has value for the local economy. In an economic study of the facility done in 2015 by MVFN member Cliff Bennett, a questionnaire was sent out all across Ontario through the ONTBIRDS network to gauge the dollar value of this magnetic draw of rare shorebirds and other birds coming in to rest and feed during migration. The results showed that during the year, 88 people had visited the lagoon, making a total of 265 visits. While in town, they spent over $4000 on gasoline, food and other shopping.  Today, the Lagoon and nature trail is regularly visited and reported on by the Ottawa birding network as well as local birders.

If you have not yet visited this facility, watch for MVFN’s series of September Open Houses at the Potvin Observation Tower. These will be held on four Wednesdays in September/October, details tba. From 3 to 5 P.M. on each of these days, an expert birder will be on site with a spotting scope to help you identify the lagoon’s visitors.

MVFN Nature Notebook Sightings

Sightings sent in July 1st and July 6, 2016:  A mystery butterfly. Or can someone confirm the identity for us?

Lise Balthazar, Sheridan Rapids

MVFN NATURE NOTEBOOK NOTE: At first we thought it might be a rather unusual sighting of a species not likely to occur here. See the first photo below which is of an individual seen by Lise on July 1st.  The other two are both of another individual butterfly, possibly the same species as the first.

First photo here is one from July 1: seen on the grass. It may or may not be the same species as the next two photos, which are both of a different individual.
