About 20 years ago we bought this gourd for the front porch and for most years we had house wrens take up house keeping and produced baby wrens. For the last few years we have had several feral cats on the porch which was cause for alarm and the females would not accept the male's invitations to settle in. The cats are gone now and the male wren, with his incessant mating call finally convinced a female to settle in with him. Today the babies hatched out and both proud parents are franticly going in and out bringing food to their new charges. I don't know how many baby wrens are in the gourd but as they get a little bigger their big mouths will be anxiously poking out of the hole trying to be the one to get the next insect brought to the nest. A few years ago, while watching the nest, I got to witness the little ones leave the nest. One by one they flew down to the railing to join the parents. Then it was over to the azaleas where they gathered with the adults who took them off to the woods so the parents could show them where to find food. Next year it will start all over again with the males, who are very territorial, building their nests and try to convince a female to join him. I'm just hoping I will be lucky again this year to see the young leave the gourd.
