Top 10 Easy Confirmations: do you have these for your block yet?

As we head into July and more eggs hatch, your focus should increasingly be on picking up those confirmed codes, with behaviors like CF (Carrying Food), FL (Recently Fledged Young), and FY (Feeding Young). Read on for a few tips on some of the easiest species you can use to pad your block totals.

Species Sponsorship: A Perfect Gift for Bird Lovers

Father’s Day is near, and the graduation and wedding season is here. If you’ve got a bird lover on your gift list, consider giving the unique gift of species sponsorship!

There are 40+ Wisconsin breeding species yet to be claimed through the Sponsor-a-Species program, a major source of support for the Atlas. Popular species like Northern Saw-whet Owl and Ruby-crowned Kinglet remain, and every dollar of every sponsorship helps support this important citizen science project.

June eBirder of the Month Challenge – Let’s get a winner from the Wisconsin Atlas!

This month’s eBirder of the Month challenge, sponsored by Carl Zeiss Sports Optics, gives you a chance to improve our knowledge of breeding birds across the world. In much of the world, June is a critical time in the annual cycle of many birds, as they build nests, hatch chicks, and hopefully fledge young—perpetuating the existence of their species. Even if June isn’t peak breeding season near you, there are still many signs of breeding to be found wherever you are! The eBirder of the month will be drawn from eBirders who submit at least 15 eligible checklists containing at least one breeding code during June. eBird Mobile now lets you enter breeding codes on your mobile checklists, so taking part is easier than ever. Winners will be notified by the 10th of the following month.

Atlaser Spotlight: Lorri Howski

Who are the incredible volunteers who make the Atlas “go”? It turns out that once you get past the binoculars—or in this case, the camera—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.

Species Survey Strategy – Colonial Waterbirds Pt. I

Certain waterbird species typically breed in colonies. Preferred spots to find colonial nesters are sites that are protected from predation like an island, a lakeshore, a beaverpond, or even in the cases of some gulls, the roof of a building. Because breeding only occurs in colonial situations, seeing these species in your block is not necessarily indicative of local breeding because they range widely, and therefore codes like H and P are generally not useful for these species. Similarly, FL and FY codes away from nest sites are not reliable because these species disperse widely once fledged.

Check out the tips in this article and then check the blocks around you for some colonial waterbirds!

Mobile Atlasing is easier than ever!

The time has come when you can submit everything you need in at Atlas checklist from just the eBird mobile app! Learn exactly how and remember that there are still circumstances when it will help to use the computer.

Nocturnal Atlasing Week 2017

Ready to hear some owls?

Atlasers throughout Wisconsin will be donning their headlamps and heading out for some night birding during Nocturnal Atlasing Week, April 21–29. This time window coincides with an early peak in owl calling, and is a good time to try to hear Barred Owls, Great Horned Owls, Eastern Screech-Owls, and Northern Saw-whet Owls, plus other crepuscular birds like American Woodcock.
