Wildlife experts at Kielder Forest in Northumberland have been tagging chicks as part of a monitoring programme for rare Ospreys.
The six week old birds were ringed by Forestry Commission rangers who scaled trees to the nest so that a harmless and unique colour tag could be attached which helps identify them.
The endangered species began to breed in the region in 2009 for the first time in 200 years.The two chicks are expected to fledge in the next few weeks.
