Welcome to Wisconsin Breeding Bird Atlas II

Birding in the 21st Century.

Explore your block with new landcover layers on the interactive map!

Wiscland 2 is a new land-cover dataset, created as part of a multiagency effort and hosted by Wisconsin DNR. They used satellite imagery to produce a map that shows different types of land cover types. When Wiscland recently became available, we added it to our atlas interactive map. If you haven’t seen the interactive map, it’s a resource you can use on your computer or your smartphone to quickly see where atlas block boundaries fall, and you can also pull up other informative layers to help you explore your block. Here we’ll walk you through what you need to know to use these layers on the interactive map.

Atlas your way to a lifer!

Is there a life bird, state bird, or county bird in Wisconsin that you really want to see? Not only is the atlas a great way to make a difference for bird conservation, but it’s also a great way to finally get you a glimpse of that nemesis species! Find out how we can help you connect with new species through atlasing.

Species Survey Strategy – Rare Forest Raptors

Two secretive resident raptors can be found across the state’s more remote, contiguous, and mature forest blocks. Wisconsin lies at the southern edge of the continental range for the Northern Goshawk, and the northwestern continental range limit for Red-shouldered Hawk. Each is a Species of Greatest Conservation Need (SGCN), with the Red-shouldered Hawk being listed as state Threatened. Both are among the earliest breeders in the state. The Atlas will play a key role in understanding the current status of these priority species. This article outlines tips and strategies to improve your chances of finding them.

To code or not to code, that is the question. Take our quiz!

With the unseasonably warm temperatures, we’re seeing some early signs of breeding activity. But are they worth entering breeding codes for yet?

Atlaser Spotlight: Pam Campbell

The Wisconsin Breeding Bird Atlas II is a volunteer-driven effort to survey the distribution and abundance of our state’s breeding birds. Since the project started in 2015, our volunteer team has grown to include more than 1,100 Atlasers who have submitted over 55,000 checklists.

Who are these incredible volunteers? It turns out that once you get past the binoculars, our Atlasers are as varied as the bird species they observe. This series turns the spotlight on a few of the many dedicated men and women who have helped the Atlas achieve such tremendous success to date.

This month, meet Pam Campbell of Dunn County!

Register Today for an Atlas Regional Kickoff Workshop

This year marks the mid-point of the Wisconsin Breeding Bird Atlas II, a critical year for ensuring we’re on track to complete this monumental effort by 2019. Help us get 2017 off to a dynamic start by joining us at one (or more!) of our FREE Atlas Regional Kickoff workshops.

These events are for everyone, whether you’re a newer member of the Atlas team, a seasoned veteran, or just want to learn more about how to join us in 2017. Each workshop will feature concurrent presentations tailored to new and returning atlasers, the opportunity to meet county coordinators and expert birders from your region, and a field trip to a local hotspot.

Come Work for the Atlas! Seasonal Technician Positions Available

Volunteers are the lifeblood of our atlas, and we couldn’t accomplish the project without them. However, every atlas must eventually start filling gaps where volunteers will not reach. If you know someone with the skills and availability to assist us in this capacity this year, either as a Point Count or Atlas Technician position, please send them this job announcement. Applications due March 1.

Atlas Effort Maps: How are we doing and where do we need help?

When we announced recently that completed blocks were displayed, we also mentioned that we are officially sitting at 14% of completed blocks, when we should be closer to 40% after completing 2 of 5 field seasons. However, if we can finish up the night effort, and convert the many “nearly complete” blocks to officially complete blocks, we’ll be close to on pace with where we need to be.

To help us see the coverage gaps, we’ve prepared some maps showing our progress so far. Recall there are 1,283 priority/specialty blocks that must be completed for this Atlas project to be a success!

Guide To Nocturnal Atlasing: Part IV – More Wisconsin Night Sounds

Our final installment of the series focuses on the rest of the species you may hear at night, which vocalize during daylight hours as well. Also addressed are common nocturnal non-avian wildlife you may hear while nocturnally atlasing.

Guide To Nocturnal Atlasing: Part III – Tips for target species

We dive into the specifics of which species to expect, where and when to expect them, and how to identify them by sound. Each species has several calls listed after the description, which should serve as both a study guide and a resource. We focus on the primary target species of nocturnal atlasing, including the owls, nightjars, American Woodcock, and Wilson’s Snipe.
