Mimicry (Ex): An ululatrix can mimic any voice or sound it has heard, anytime it likes. Listeners must succeed at a Will save (DC 17) to detect the ruse. The save is Charisma-based.

Sonics (Su): An ululatrix can produce several powerful sonic effects. When it uses a sonic attack, it must wait 1d4 rounds before using another one. All the effects listed below are sonic effects except for the trill, which is a sonic, mind- affecting effect.

Dragon Traits: An ululatrix is immune to sleep and paralysis effects. It has darkvision (60-foot range) and low-light vision (sees four times as well as a human in low-light conditions and twice as well in normal conditions).

Immunities (Ex): An ululatrix's sense of hearing, and indeed is entire body, is protected from sonic shocks of all kinds. Also, its own mastery of sound mimicry makes its sensitive to false or misleading sounds. These qualities make an ululatrix immune to any sonic effect.

Scent (Ex): An ululatrix can detect approaching enemies, sniff out hidden foes, and track by sense of smell.

Skills: An ululatrix receives a +8 racial bonus on Hide checks, thanks to its variable coloration.

Feats: If an ululatrix gets a hold on a creature two or more sizes smaller than itself using the Snatch feat (grapple bonus +28), it can pick up the creature and fly away with it. A creature that is flung by an ululatrix after being snatched travels 30 feet and takes 3d6 points of damage. If the ululatrix is flying, the creature takes this damage or the appropriate falling damage, whichever is greater.
