NestWatch: 7 Wren nestlings

One of the nestboxes we watch is used this Spring by House Wrens Troglodytes aedon.  Seven eggs hatched on June 8.  Today the cam recorded the adults feeding three times within two minutes.  The adult Wren is only 4.5 to 5 inches long.  She feeds spiders, beetles, caterpillars, earwigs, flies and other insects to her tiny hatchlings.  (MP4 video)

In this video, you can see the wriggling legs of the insects she brings in.  Wrens keep their nests clean; they wait for the young birds to expel a fecal sac (birdie diaper, poop bag).  Until the young birds are 4 or 5 days old, the parents may eat the sacs since the baby's digestive tracts are not very efficient and the sacs may still contain nutrition.  Later, they'll carry them away from the box and drop them. This way, the nest lining stays clean and healthy for the crowded clutch of young Wrens.
