Concerns have been raised after the possible disturbance of a peregrine falcon's nest in the Forest of Dean.
Police have released an image of a man they want to speak to, who was seen climbing over a cliff near the nest on 24 May:
Disturbing the nest risks the birds failing to breed this year.
Peregrines are a protected species, and it's a criminal offence to kill or injure one.
It is also an offence to "intentionally or recklessly disturb the birds" close to their nest during the breeding season.
The intentions of this male are as yet unknown but it is clear that there would have been disturbance to the peregrine nest at this critical time.
Officers are working with Gloucestershire Wildlife Trust and the Gloucestershire Raptor Monitoring Group to identify the man and establish his intentions.
There are only a small number of nest sites in the county.
Pet owners in the Forest of Dean are being urged to be extra vigilant after a dog got its head caught in a snare.
The illegal snare became entangled around the dog's neck while in Staple Edge Woods at about 10am on May 30.
Luckily the owner was nearby and able to free her pet before too much harm was caused.
The illegal snare, which was tied to a tree and hidden in undergrowth, was home made with a metal noose and rope.
The rope from was tied to a tree with the metal noose propped up and open, so the dog ran straight into causing it to tighten immediately. Luckily the owner was nearby and released the dog, but it could have been much more serious, strangling the dog or even having a child run into it.
I would urge other people walking in woods to be very careful and to keep an eye on their dogs.
Police have urged anyone to report snares they may find, or any information which would help us find the people responsible.
