An ultrasonic whistle apparatus for mounting on a vehicle to warn animals of the approach of the vehicle, comprising in combination:

• (a) a funnel for directing air into the apparatus and having an air path therein;
• (b) an ultrasonic whistle mounted in the air path in the funnel and adapted to be actuated by air passing therethrough;
• (c) a base for mounting the apparatus to a vehicle comprising:
• (1) a spring section having a groove formed therein for slidably receiving a key, the spring section comprising a spring disposed in the groove which is based upwardly and which has a button on an uppermost portion thereof;
• (2) a socket section which is slidably engagable in the spring section and which has a lower surface with a recess formed therein which retentively receives the button therein to disengagably retain the socket section in the spring section;
• (d) a key for disengaging the socket section from the spring section, the key having a substantially parallelepiped operative end, whereby the operative end of the key may be slidably inserted into the groove, thus pushing the spring downwardly to disengage the button from the recess and enable the socket section to be slidably disengaged from the spring Section, and
• (e) an adjustment means connecting the funnel to the base;
• the adjustment means comprising means for adjusting the direction in which the funnel is oriented, said adjustment means being adjustable in more than one plane of adjustment.
