Like many birds, barn owls like to nest in cavities (i.e., holes or hollows in trees, in nest boxes, etc.). However, barn owls do not typically build or construct their nests in the typical sense. All they need is a flat or concave surface on which to lay their eggs, often in a cavity or on a wide ledge (like the flat top of a wall or the upper floors of a church tower, or even...the inside of a barn!). As long as the correct surface is available, who needs to bring nest construction materials? Not a barn owl! Instead, female barn owls are quite the little homemakers. They will take owl pellets (regurgitated bits of their undigested food that they cough up in pellet form), shred them apart with their talons, and shape the pellets into a cup to line the bottom of the nesting surface. These nests can be re-used season to season, so the layer of pellets in the nest builds up to several inches thick over time. The pellets will get compacted over seasons of use, which helps to provide a dry, soft pad for the bottom of the nest. No new building supplies required!
