The new Status and Trends from eBird drills further down into current information, showing areas where declines are sharpest:

The abundance map demonstrates how numbers have dropped in many areas of the core range of this species:  https://ebird.org/wi/science/status-and-trends/norbob/abundance-map

One organization devoted to conservation of this species is the National Bobwhite Conservation Initiative. Learn more about their efforts at:  https://bringbackbobwhites.org/

How to protect habitat for declining Bank Swallows

Bank Swallows use sandy or clay banks in many settings in which to excavate a nesting cavity. Bank Swallows are experiencing a population decline. The BBS trend for this species in Wisconsin is displayed below.

the sprite of the ponderosa pines


One of my favorite mountain forest birds is this tiny sprite of the ponderosa pines: the Pygmy Nuthatch. A small flock flits between pines and moves about trunks and limbs, sometimes on the ground. These small flocks  even spend nights all together in a single cavity in the non-breeding seasons. It's another of the species that sometimes has young of a previous breeding season returning to their parents and acting as  "helpers at the nest", assisting in raising young. Learn more about them at https://www.allaboutbirds.org/guide/Pygmy_Nuthatch/id
