Help Us Monitor Chicagoland's Breeding Birds

Becoming a BCN Survey monitor is one of the best ways that you can make a valuable contribution to birds in your area.

What's Involved

01.

Set Up Your Points

Monitors should have experience identifying the expected breeding birds at their points by both sight and sound, as well as be able to safely go off-trail through vegetation and over uneven terrain. You will work with a BCN Area Coordinator and may also need to register as a volunteer with one of our partnering land managers. We will help you set up the locations of your monitoring points, enter data in eBird, and get established as a volunteer. If you are monitoring an existing location, your point locations will already be set up for you.

02.

Visit Twice in June

You can contribute your sightings simply by visiting a site at least two times in June and following BCN Survey protocols to count birds there. Some land managers may ask for additional visits, and birders are also encouraged to optionally visit their site(s) during other seasons to track migrant and wintering birds.

03.

Start Close to Sunrise

Monitors are encouraged to start as close to sunrise as possible. During the month of June, sunrise ranges from 5:15 a.m. to 5:19 a.m. Surveys should be completed by 9:00 a.m. at the latest.  Bird activity will drop off considerably after about 7:00 a.m. or 7:30 a.m. on a warm day.

04.

Visit Each of Your Points

Monitoring will be similar to normal birding except you will stand still for five minutes at each point at your site to count all the birds you see and hear within a specific radius of where you are standing. Points are also often located out in the habitat rather than along a trail. The number of points you monitor will vary, but generally range between four and ten points.

05.

Identify Birds Seen and Heard

Monitors record all birds seen or heard within the radius of the point count. Flyover birds should only be counted if they are below treetops and/or using the habitat within the point count circle.

06.

Submit Your Data

Birders familiar with eBird will enter data much like normal except each point is set up as a separate location and other incidental sightings and flyover birds not using the site are recorded separately. Data is also entered using a special BCN Survey protocol in eBird. Some land managers may have other data entry requirements.

History of the BCN Survey

Standardized, Coordinated Bird Monitoring in Chicagoland

BCN coordinated standardized monitoring that was implemented in a 1998 effort that transformed monitoring practices in the Chicagoland region.

The initiative was spearheaded by BCN members Judy Pollock, Alan Anderson, Terry Schilling, Lee Ramsey, and Elizabeth Sanders, with major participation from a group of dedicated birders, scientists, land managers and conservationists including Jerry Garden (Chicago Audubon Society), Jerry Sullivan (Cook County Forest Preserve District), Doug Stotz (Field Museum), Stephen Packard (Audubon - Chicago Region) and Dan Niven (Illinois Natural History Survey).

Prior to 1998, monitoring by citizen scientists had been active in the Chicago region since at least the 1980's, but a lack of standardized protocols and the daunting task of entering reams of data into digitized files meant that much of the information amassed over the past years remained inaccessible and difficult to analyze.

Bobolink

Online publication and quick analysis of our data became a reality in 2001 when Cornell Lab of Ornithology's BirdSource teamed up with BCN and the Field Museum to unveil a new website. This site came about thanks to the efforts of Debby Moskovits and Doug Stotz (Field Museum), Terry Schilling, Lee Ramsey, Alan Anderson and Suzanne Checchia (BCN volunteers), Steve Kelling and Michael Brutvan (Cornell Lab of Ornithology) and Judy Pollock, Rickie White and Steve Frankel (Audubon-Chicago Region).

Joining eBird in 2003, the BCN database moved to a special BCN version of the eBird website, a nationwide site for data entry managed by Cornell Lab of Ornithology & Audubon. This move provided us with easier access to data for research purposes and casual observations, and also allowed BCN monitors to easily enter their sightings at any of the predefined birding hotspots in the Chicagoland area.
