The boy who clipped the right wing asked permission to take the raptor home to 1LT K.M. Esperanza of The Philippine Armys 80th Infantry Battalion at Baras, Rizal. But later surrendered to the army and and turned-over by PFC J.P. Castillo to PENRO Rizal.
The Besra was found released by DENR to the wild because of the numbered metal tag attached to its leg. It is used for individual identification and movement tracking of a wildlife species.
