Abstract - Nest site characteristics are described for 94 honey bee nests in trees, 17 in the ground, and 82 in man-made structures. Nests were in trees of mean diameter 85 cm primarily in live hardwoods, especially oaks. Entrances were mostly single knots or cracks in the main trunk at ground level and up to a mean height of 2.5 m. Most nests in the ground were in treeless areas; half had partially exposed combs, possibly aiding ventilation. Nests in buildings differed from those in trees by having smaller entrances. Compass orientation of comb in natural nest sites was commonly from 145° - 195°.
