Timandra (mother of Neophron)
in Greek mythology, Timandra () is a widow woman who became the lover of Aegypius. Mythology 
Her son Neophron disapproved of the affair, so he seduced Aegypius' own mother Bulis. He brought Bulis into his house, made sure his own mother was out, and then arranged for Aegypius and Bulis to sleep together, unsuspecting of the other's true identity. The moment they found out the trick, Aegypius prayed that he would vanish, and Zeus turned all four into birds. Timandre changed into an aegithalos (), now the word for "long-tailed tit", but the Greek bird may have also been any of the Paridae. References
