Hedgehog spotted in Forest as juveniles disperse across Brussels
July 27, 2026
(Erinaceus europaeus) turned up in Forest on July 25 — an unverified record (needs_id) but the second sighting this summer, after a research-grade observation in June, and part of a scatter of four records across Brussels green spaces over the past two years.
July is juvenile dispersal season: young from spring litters push out of their birth sites, crossing roads at dusk and moving between gardens and park margins to stake out new territory.
The species has declined sharply across western Europe, squeezed by traffic, pesticide pressure on invertebrate prey, and the loss of rough, unmanaged ground for shelter. These sporadic sightings across the city's patchwork of gardens, churchyards, and small parks suggest some corridor of movement still exists — but four records over two years is a thin thread, and iNaturalist flags this species as threatened throughout the region.
On a warm night in early summer, a salamander moving through the litter near a damp log is visible if you look slowly. The yellow and black patterning is not camouflage. It is a warning, advertising the toxic skin secretions the animal produces. Predators that have encountered one before avoid them. The pattern works because it is memorable, and it is memorable because it is so distinct: broad irregular patches of yellow against black, varying between individuals, consistent enough as a signal to be recognized. If you are out after dark near any of the older, damper tree stands at Pentagone, you might crouch beside a mossy log and wait. The salamander will come to you before you find it. Right now the ground is cool and damp beneath the canopy, and somewhere in that darkness a tongue is already working.
