Animal Tracks in the Snow

Animal tracks: Fox, Crow, and Squirrel prints on a snowy boardwalk
Animal tracks: Fox, Crow, and Squirrel prints on a snowy boardwalk

Today we woke to a snow-covered city, just a light dusting; and as often with snow, the weather was appreciably warmer than before the snow arrived.

Down at the nature reserve,  the paths were empty of human footprints, but thickly sprinkled with animal tracks. Here some crows had walked to and fro across the path; there, a fox had jogged along the trail. But better was to come: the boardwalk across the pond was interlaced with tracks. On the left, a fox had gone the length of the boardwalk. In the centre, a crow had walked unsteadily along, the same way as me; and it, or another, had walked more rapidly back. On the right, more birds’ footprints: and the four-feet-together group of a squirrel, the smaller front prints clearly showing the marks of the sharp claws.

On a Birch branch above the anthill meadow, a Green Woodpecker hammered in search of food. Down by the ‘mangrove swamp’, a Jay screeched harshly, either for us or for a fox. Near the picnic meadow, a Sparrowhawk flew from its high perch, wheeled above the treetops, dived rapidly out of sight.

We carried tools and a ladder to visit the nestboxes and take down all that needed repairs. While I held the ladder, a party of four Long-Tailed Tits blew by, crossing from one Birch to the next one at a time. One of the boxes contained not just a mossy nest (like three others) but two old addled eggs, probably of Great Tit. While we struggled to prise off a somewhat too well attached box for maintenance, a Robin perched nearby, in hope of eating any grubs we might have disturbed. Several boxes had had their openings enlarged by much hammering by Blue Tits or Great Tits: nobody knows why they might do this, as it increases the threat to their nests from predators. We will make aluminium plates for the fronts of all the Tit boxes (the ones with circular holes): the Robin boxes just have a wide rectangular opening, which they definitely prefer. Inside one of the boxes was a mass of woodlice in the moss; another had a plump dead Noble False Widow Spider (Steatoda nobilis) inside.

Natural History

Is that a Noble False Widow spider, then?

Well, it was certainly a large and striking spider with a distinctive crescent mark on the forward slope of its abdomen, so “False Widow Spider?” sprang into my mind. It was, amusingly, making itself conspicuous on the noble bronze surface of the Henry Moore statue in Kew Gardens: there’s just one now, reminding old-timers of the ‘one behind every bush’ feeling we had in 2006 when the gardens were full of Henry Moores, and I confess I pretty much ‘understood’ what they were about for the first time, seeing them against a natural (well, you know what I mean) background as massive, handsomely curved figures. One was near a splendidly branchy conifer, its huge curved branches setting off the sculpture.

But I digress. The spider had a finely moulded cephalothorax and a large, nearly globular abdomen, marked with a sandy crescent and a dotted area. Its legs were distinctively reddish. Back at home, I looked up images of false widows. It certainly wasn’t the large native False Widow, Steatoda bipunctata. It looked much like the introduced Steatoda nobilis; perhaps the dotted area on the abdomen was not typical, but it seems close enough. The species, according to the Natural History Museum, arrived here in the 1870s — not quite such a new arrival as the ebola-panicky tabloid newspapers seem to think, then. It most likely arrived among bananas from Madeira and the Canary Islands, so it really is a subtropical scary. It can “live comfortably in our homes all year round”, says the museum cheerily, and is now common and widespread. And yes, it does bite; but the effect is not much worse than a wasp sting. I suspect a bit of hydrocortisone cream would sort it out nicely. Or a swift tap with a shoe, of course.
