A surgical tech is a professional who assists surgeons in the operation theatres during surgeries. In a nutshell, their responsibility for a surgery starts with preparing the operation room for the surgery and ends with post operation care of the patients.
Jays are very territorial birds, and they will chase others from a feeder for an easier meal. Additionally, the blue jay may raid other birds' nests, stealing eggs, chicks, and nests. However, this may not be as common as is typically thought, as only 1% of food matter in one study was bird material.
On the ground and in shrubs and trees, blue jays feed on caterpillars, grasshoppers and beetles. They also eat flying insects from the air. Sometimes they store food in caches and eat it later. They have been known to feed on injured or dead mammals and birds.
