Wildlife Conservation Organizations

National Bird Conservation Initiatives

The following entities are collaboratives among agencies, non-profits, and other groups. Some are focused on a particular subgroup of birds.

Bringing Birds Back

Includes links to the 2019 Science paper mentioned in the introduction.

The North American Waterfowl Management Plan

The oldest of the bird initiatives, formed in 1986, primarily concerned with the conservation of ducks, geese, and swans.

Partners in Flight

Assumes responsibility for conservation planning for landbirds, a broadly defined group that includes all species other than shorebirds, waterfowl, waterbirds, and resident game birds.

US State of the Birds

Here you can find copies of the national State of the Birds documents.

The Shorebird Group

Works to conserve North American shorebird populations through a combination of research, monitoring, and conservation planning.

Waterbird Conservation

Focused on a broad selection of wetland and marine birds that includes colonial waterbirds (e.g., herons and terns), marshbirds (e.g., rails and bitterns), and other solitary species such as loons.

Bird Population Data Sources

The resources listed below (among others) are vital tools to assess the health of bird populations both in New Hampshire and across North America.

Species & Habitat Data Reference Tables

The Breeding Species table includes all species that have bred in New Hampshire over approximately the last two decades.

Italics = Rare or irregular breeders

B = Habitats in which a species breeds

N = Additional habitat where the species occurs during migration or winter

The Non-breeding Species table includes species that are roughly annual in occurrence during migration or winter but do not breed here. x = Habitats used during migration or winter

If a species in either table is considered a Species of Greatest Conservation Need (SGCN), it is assigned one of the following categories:

X = Species listed as an SGCN in the 2015 New Hampshire Wildlife Action Plan

SC = Special Concern in NH

T = Threatened in NH

E = Endangered in NH

R = Considered a Regional SGCN in the northeastern United States (only shown if a species is not in any of the previous categories)

General Trend:

II = Strong increase

I = Moderate increase

S = Stable

D = Moderate decrease

DD = Strong decrease

U = Unknown
