I have a House Wren nest on my deck. The house was supposed to be decorative, but this is the second year the wrens have used it to raise babies. From what I've seen, the main dish offered are spiders!!! Occasionally small butterflies also.

Excellent! I watched a female packing in nesting material to a nesting box. A busy as I've seen a bird, a trip every 30 seconds or so. Too far for pictures without spooking her.
The house Wrens use sticks for their nest material...and they will put those sticks into every nest box they can. I have to keep emptying those sticks from the BB houses.

An interesting fact from the Cornell Ornithology Lab website:
  • House Wrens nest inside tree holes and nest boxes. As the season progresses their nests can become infested with mites and other parasites that feed on the wren nestlings. Perhaps to fight this problem, wrens often add spider egg sacs into the materials they build their nests from. In lab studies, once the spiders hatched, they helped the wrens by devouring the nest parasites.
