On November 24, 2024 I was proceeding north at speed on County Road 24 through Prince Edward County, Ontario, Canada when I saw a small herd of cows. I glanced over and gave them a quick pro forma check for a Cattle Egret as I passed by. I've been doing this for years and years, never with any success.
Although Cattle Egrets are very rare hereabouts (they are a tropical to semi-tropical species), they do have a pattern of late fall incursions into southern Ontario from the USA. So, when I saw a small, bright white, angular shape on the ground amidst the cows I decelerated rapidly, pulled over, and backed up. There it was ... a Cattle Egret! A great birding moment after imagining the encounter for so long.
As noted, Cattle Egret are pretty rare in Canada but they do sometimes show up in November, which is a bit odd for a warm weather bird. When they do appear, they are often seen associating with cattle (hence the name) and feeding on the insects that the cows stir up. So what is going on?
Cattle Egret are not native to our continent, but arrived in South America from Africa in the 1870s, probably carried across the ocean on hurricane winds. They did well and by the early 1950s reached North America, where they have thrived in the warmer south, but not so much in colder Canada. Perhaps the birds are still carrying an Africa navigation chart in their DNA that tells them to head north in November to find better habitat in their old home. Unfortunately, this program is suboptimal here, sending them north into freezing temperatures. Hopefully the bird will reorient itself. In the meantime it seems it found a new friend.
