Brown-lipped Snails at Thomson Park: Sept. 21, 2022

The Brown-lipped Snail (Cepaea nemoralis) is named after the brown band of colouring found around the opening of the shell. It is one of the most common species of land snail in Europe, and has been introduced to North America. This snail is comparatively slow-growing, usually taking three years to develop from an egg to a breeding adult. The life-span for this species is up to seven or eight years. In winter, the snails may hibernate, but can become active again during warm spells. (

We saw several this morning.

Hi Miles,

How can these birds do it? Fly all the way across the Pacific without feeding or taking a break. The fact that they can shrink their organs and increase their pectoral muscles before they go is amazing!

The Godwit’s Long, Long Nonstop Journey

The Godwit’s 7,000-Mile Journey: A Migration That Breaks Records – The New York Times (


To grass, or leaf, or fruit, or wall,
The snail sticks close, nor fears to fall,
As if he grew there, house and all

Within that house secure he hides,
When danger imminent betides
Of storm, or other harm besides
                                                Of weather. – William Cowper (1731 – 1800)
