From a much longer Associated Press article, this excerpt tells why Egypt wondered if someone outside of Egypt was spying from overhead.

CAIRO (AP) – In a case that ruffled feathers in Egypt, authorities have detained a migratory bird that a citizen suspected of being a spy.
A man in Egypt’s Qena governorate, some 450 kilometers (280 miles) southeast of Cairo, found the suspicious bird among four others near his home and brought them to a police station Friday, said Mohammed Kamal, the head of the security in the region.
There, officers and the man puzzled over the electronic device attached to the suspected winged infiltrator. On Saturday, a veterinary committee called by concerned government officials determined the device was neither a bomb nor a spying device.
Instead, they discovered it was a wildlife tracker used by French scientists to follow the movement of migrating birds.
