Neighborhood Nestwatch comes to Denver!
Is that Black-capped Chickadee at your feeder the same one you see every day, or is it a different one? Is that a male or female robin? Is the House Wren using your nestbox the same one that took up residence last year? Are there birds nesting around your home? Neighborhood Nestwatch answers these questions and more, bringing Bird Conservancy of the Rockies biologists to backyards in the Denver area to gather scientific data about local birds and train participants to become citizen scientists. As a participant, your backyard becomes a scientific study site as you learn about the process of science and report critically needed data. Data gathered by participants goes to the Smithsonian Migratory Bird Center (SMBC) and helps scientists study the effects of urbanization on nesting success, annual survival, and other variables. This program is a terrific way for people to connect with nature’s wonders right around their own home while also making meaningful contributions to science.
Neighborhood Nestwatch was created in 2000 by Dr. Peter Marra of the SMBC based at the National Zoo in Washington, DC. Since starting in Washington D.C., the program has expanded to seven cities including Pittsburgh, PA and Atlanta, GA., with hundreds of participating homes. The Denver “hub” of the program begins this year and is the first location west of the Mississippi River. For more information about the national Neighborhood Nestwatch program, click here.
Nestwatch Denver will focus on six target species (pictured above and listed in order, below):

- Song Sparrow (photo by Jon Delorenzo)

With support from SMBC, Bird Conservancy will first ensure that your yard is a suitable site for this program based on a yard’s unique combination of its surrounding landscape and location relative to other Denver sites. Keep in mind these criteria have little to do with how citizens manage their yard. Selected backyards can be surrounded by development, agriculture, pristine woodland, or everything in between. In addition, sites must be located within 50 miles of the Denver Museum of Nature & Science. Volunteers must also be willing to participate in the program for at least three years and are expected to make efforts at contributing data to the program.
What happens during the site visit
Bird Conservancy staff start conducting activities in your yard around 7 a.m. After completing a bird census at your yard, mist nets are used to capture birds for banding. Target species are color-banded, and their health information recorded. Bird banders also search for any nests in your yard and inventory plant species to help understand the habitat. Finally, Bird Conservancy staff will spend some time conducting a detailed characterization of the plants in your yard. Your active participation during the visit is truly welcomed! Except for the initial bird census, the staff will accommodate your assistance in aspects of the visit. At the end of the visit, you will receive a listing of “your” birds with their corresponding color band combinations. Throughout the visit you will learn exciting facts about birds and science including the tools you will need become a citizen scientist. Visits typically take about 6 hours.
Neighborhood Nestwatch focuses on two basic life history traits: annual survival and reproductive success. Participant data from re-sightings of color-banded birds reflects how long birds live within their yard and nearby surroundings. Nest monitoring through the program provides information about bird reproduction across the study region. When participants submit their data, important comparisons can be made regarding annual survival and nest success for individual species.
Neighborhood Nestwatch is offered in collaboration with the Denver Museum of Nature & Science (DMNS) and Smithsonian Migratory Bird Center, and with the support of the Science & Cultural Facilities District (SCFD) and Adams County, Colorado.
