In a remarkable example of natural engineering, beavers constructed a dam that filtered polluted water flowing into a protected area—achieving what local authorities had spent seven years planning but had not yet implemented. The animals unknowingly completed the project for free. The beaver dam slowed water flow, trapped sediment, and prevented contaminated runoff from spreading downstream. When officials inspected the site, they realized the dam accomplished the same environmental goals as a p

Beavers make scent mounds to mark their territory. This beaver jumped on a rock, left mud and debris, and then sprayed her scent (a mixture of urine and castoreum). There were lots of excited spectators on the sidewalk, as you can hear. You can see the beaver’s scent spray when she turns to leave. You will also note that this beaver, who I have named Palmer, has very unique tail damage from an old injury. #cuteanimals #wildlife | Mike’s photos and videos of beavers

Beavers spray their scent (a mixture of urine and castoreum) to mark territory. Scientists also believe the scent conveys information like the sex and age of the beaver, which may assist in two year olds finding a mate. In this video, a beaver that appears to be a two year old, seems very interested in the scent that Palmer left on this rock. Maybe love is in the air. 😀❤️🦫 #beavers #wildlifephotography | Mike’s photos and videos of beavers

Watch this beaver demonstrate the technique for making a scent mound to mark its territory. The beaver first scoops as much mud as it can, then walks upright looking for just the right spot, then drops the mud, scatters it a bit, and sprays its scent on it. #beavers #funnyanimals | Mike’s photos and videos of beavers
