TFN is Moving!
Posted September 2017
After many years residence at the 2 Carlton Street office TFN is moving to 2449 Yonge Street, which is about 400 metres north of Eglinton subway station, at the south east junction of Yonge and Erskine Avenue. The new office is a bit smaller and slightly less convenient to reach, but is certainly adequate to our needs. The lower rent will help to keep TFN financially viable. The first day of occupancy will be November 1, 2017. TFN office-related activities will continue as before and members are free to visit us on Friday mornings or on any other weekday by appointment.
Tagging Monarchs at the CNE
Posted September 2017
TFN members Anne Purvis and Margaret McRae spent 2 afternoons at Scadding Cabin at the CNE in late August tagging monarch butterflies and talking about raising butterflies. They showed pupas, small and large caterpillars. The event was a success with close to 300 observers in the 2 days including many children. One butterfly emerged overnight another emerged in the afternoon which thrilled the people watching. Usually Margaret tags butterflies that she raises at home so catching them is easy as they are caged. At the CNE she had to catch them outside in order to tag them which is much trickier. Fortunately Carol Sellers was able to lend Margaret a net. Finding butterflies on the first day was easy but the second day was cooler and cloudy and they didn't catch any until the late afternoon when the sun came out. Many thanks to Margaret and Anne for educating people on the plight of butterflies and what individuals can do to help.
Creating a better bird collar?
Posted September 2017
Domestic cats are responsible for about 196 million birds death every year. Campaigns aimed at cat owners in an attempt to convince them to keep their cats indoors have only been moderately successful, so there is a market for products that let cats roam around but prevent kills (e.g., ultrasonic devices). Simply putting a bell on a cat's collar causes birds to return with 41% fewer birds than cats with a plain collar. But to really make a difference in a cat's kill rate, outfitting your cat with a Birdsbesafe collar reduces the return rate to 87% fewer birds according to a study in Global Ecology and Conservation. The Birdsbesafe collar also reduces small mammal kills but is not as effective at that. The collar's colours are specifically designed to be highly visible to bird vision and the product's aesthetic is designed to be acceptable by cat owners. The latter is important as products like CatBib which, though effective, are bulky and unappealing to owners. Still, the best way to protect birds from pet cats is to keep them indoors.
