Common Tansy / Tanacetum vulgare

On 16 August 2015, I went with a group of friends to Carburn Park to look for Warblers and several species were seen by at least some of the group. Group size was much too large even after splitting in half, but I think everyone was so thankful that it wasn't raining, unlike the previous day of heavy rain, that they came out to enjoy the sunshine. I enjoyed seeing a Merlin, a number of Double-crested Cormorants, and several Pelicans that flew overhead. Without binoculars, I didn't really see any of the Warblers, except for a quick glimpse of one Yellow-rumped Warbler.

As you can see from this photo, my eyes were not always looking upwards : ) On any birding walk, I'm always looking around me to see what else there is to photograph. We tend to walk on such uneven ground, that my eyes are mostly downwards anyway, making sure I don't catch my foot in a hole or go flying over a fallen branch or log.

This Common Tansy plant was growing along the edge of the path. Though Common Tansy (Tanacetum vulgare) is a noxious weed that grows in our natural areas, I still like coming across it, with its beautiful bright yellow, button-like flowers.

"Introduced from Europe in the 1600’s, its pungently aromatic foliage has been used medicinally, as an insect repellant, and for embalming. Common tansy forms dense stands and the plants contain alkaloids that are toxic to both humans and livestock if consumed in large quantities. Cases of livestock poisoning are rare, though, because tansy is unpalatable to grazing animals. Because of its long medicinal and horticultural use, Common tansy is still available in plant nurseries and from herbal remedy suppliers. Gardeners should not purchase Common tansy."
