New Jersey’s Songbirds

New Jersey’s Songbirds

There are 150 different species of songbirds in New Jersey, and majority of them are Neotropical migrants – those that breed in temperate areas of the US and Canada and migrate long distances to winter in tropical areas of Mexico and Central and South America, or in some cases further south. Birds such as the upland sandpiper (technically a shorebird), golden-winged warbler, northern parula, wood thrush, scarlet tanager, cerulean warbler, and bobolink are Neotropical migrants. Short-distance migrants, those species that breed in the US or Canada but only travel a few hundred miles or less for the winter, include robins, most sparrows, eastern towhees, and bluebirds.



Of the 150 different species of songbirds in New Jersey, six are endangered, five threatened, 25 special concern, and an additional 35 are Species of Greatest Conservation Need (pdf, 335kb). Many more birds are declining, however, as evidenced from the 3 Billion Bird Decline – some species have lost 60-80% of their population since 1970. These declining bird species are comprised of a mix of Neotropical and short-distance migrants, along with a few residents. The majority of the declining bird species, including many of New Jersey’s endangered, threatened, and special concern songbirds (below), utilizes forests, and/or grasslands for breeding or post-breeding.




Because these declines are linked to habitat loss on the breeding grounds, NJ Fish and Wildlife focuses habitat restoration efforts on forest and grassland habitat types.

Forests

Forest songbird habitat projects are being implemented on public and private lands in northern New Jersey. Out of the 59 forest bird species that breed in New Jersey, 31 of them are declining, and 30 of those declining species either breed in open-canopy forests filled with shrubs, saplings, and herbaceous vegetation, or bring their chicks to open-canopy forests filled with shrubs and saplings after leaving the nest. Songbirds suffering the greatest declines like the eastern whip-poor-will, golden-winged warbler, cerulean warbler and field sparrow have all been observed in areas where the closed-canopy forest was extensively thinned via silviculture to make an open-canopy forest. Even birds associated with closed-canopy forests, such as the pileated woodpecker and the endangered red-shouldered hawk, are seen using these areas for breeding or foraging.



Grasslands

Warm-season grassland

Grassland songbird habitat projects are also being implemented on public and private lands. Mainly through the conversion of agricultural land and cool-season grasses to a fallow or warm-season grass mix, these projects readily attract declining songbirds like bobolinks, grasshopper sparrows, and eastern meadowlarks.

Volunteer Opportunities!

Experienced birders (both sight and sound) are needed to volunteer to fill vacancies in the North American Breeding Bird Survey (BBS). The BBS is a long-term, international avian monitoring program to track the status and trends of North American bird populations at the national, regional, and state scales. New Jersey has 27 survey routes in total and vacant routes can be checked online. A summary about the BBS is below:

  • Each survey route is 24.5 miles long with stops at 0.5-mile intervals.
  • Surveys are conducted on a single day, usually during the first half of June.
  • At each stop, a 3-minute point count of all birds seen and heard is conducted.
  • The data are most useful when the same observer runs the route for several years, so we encourage people to make a commitment to run their routes for at least the three consecutive years, preferably longer.
  • Volunteers must have suitable transportation to complete a survey, good hearing and eyesight, and the ability to identify all breeding birds in the area by sight and sound.

New Jersey Fish and Wildlife’s Endangered and Nongame Species Program provides coordination for the BBS in New Jersey. For more information, contact Sharon Petzinger.
