Sitta pygmaea

September – Colorado

L=4.25” ...... WS=7.75” ...... WT=0.4 oz Order: Passeriformes (Passerine Birds) Family: Sittadae (Nuthatches)

Nuthatches acquired their name due to their habit of placing a nut or other hard food item in a bark crevice and hammering it until it opens thus “hatching the nut”. Hatch is thought to be a corruption of the old English term hack. Pygmy Nuthatches roost in tree cavities which are picked for insulation and ventilation according to the season. Additionally, they are capable of controlled hypothermia and will have communal roosting to retain heat during cold periods.
