Made from 100% sisal (agave sisalana), our barbet nesting logs offer your garden barbets the perfect garden residence. Both adults excavate the hole in the nesting log, creating an entrance tunnel and an enlarged nesting chamber. And they do so very swiftly! Barbets are arboreal birds which nest in tree holes, laying their eggs between September and December. 1 to 5 eggs are laid at daily intervals, with incubation lasting between 13 to 17 days. Our barbet nesting logs have a life-span of around 12-18 months.
