This coming weekend is the 7th annual City Nature Challenge in the Calgary area, organized by Matt Wallace. During this four-day event, particpants will document urban biodiversity on the iNaturalist app and website. Anyone can take part anywhere within the competition area:

Although this is a fun and educational activity, and a friendly competition between hundreds of cities around the world, recording our biodiversity is critically important to the cause of conservation. As birders, many of us record our sightings on eBird, which is great for research into bird populations. But when it comes to governments and industry making changes to the environment, iNaturalist is the database that is most often used, as it provides a critical understanding of our complete biodiversity so that we can make responsible development decisions. In the first six years of the Calgary CNC, over 40,000 observations have been made. This is a great start, but we can do much more to fully document our species and to fill in the map with observations. Go to the Calgary CNC website for more information, and watch the video below:

Anyone can use the iNaturalist app on their smart phone or the iNaturalist website on their computer at any time of year to contribute to our biological knowledge. But the CNC is a great time to learn how to do this. There are many resources on the CNC website about how to use iNaturalist, how to take good identifiable photos, and how to upload your observations (you have until May 4th to upload your observations for this project, so you can use this weekend to just make as many observations as possible, and upload them later). See the detailed page about iNaturalist too.

There are many events planned for the upcoming weekend as well:

Friday April 25 – Frank Lake Bird Walk, Nose Creek Bioblitz Walk.

Saturday April 26 – Nature Walk at North Glenmore Park, Guided Photo Walk in the Weaselhead, Bragg Creek Bioblitz, Documenting Glenbow Ranch Provincial Park.

Sunday April 27 – St. Patrick’s Island Nature Walk, Nose Hill Community Pollinator Walk.

Monday April 28 – The Plants of Britannia Slopes.

Please see the CNC Events page here for more information and to register for any of these events. Bring your camera and phone, learn about our natural areas, and help us reach our goal of 15,000 observations this weekend.

eBird Counties of Southern Alberta

Feb8

Posted by Bob Lefebvre

If you are a birder in the Calgary area who uses eBird, you may be confused about where the boundaries for the eBird Counties are. As you enter sightings from various locations in the region, you will see that some are assigned to Calgary County, and some to Drumheller, Banff, Lethbridge, or others. It is not clear at first what these counties represent. Even when we were doing the 2015 eBird Competition we were not sure what to make of the eBird Counties.

It turns out that the boundaries for eBird Counties in Canada follow the federal government’s Census Geographic Units. This is not a well-known political or geographic entity, and the boundaries are not marked anywhere as you travel around. (In the United States, where eBird started, the eBird Counties are the same as the political Counties, which are well-known and have well-marked boundaries.)

However, it is possible to see a map of our County boundaries by going on Google Earth. If you don’t have Google Earth you should download it. It is free, and very useful for birders. You can see satellite maps of the entire world down to a very fine level.

When you are on Google Earth, zoom into the region you want to see, and turn off all the layers except “Borders.” The fine green lines on the map are the county boundaries. (Thanks to Dan Arndt for finding out what the counties are, and how to see the boundaries.)

Feel free to copy this map as a reference, but I do recommend downloading Google Earth, so you can zoom in to see the boundaries at a finer scale. You can also turn on other layers such as “Places ” and “Roads” so you can see where the towns and highways are.

Below are four detail maps of the north, east, south, and west edges of Calgary county.

The east side of Calgary County, along the Trans-Canada Highway. Drumheller County begins immediately east of Weed Lake, and actually includes part of Dalemead Reservoir.

The eBird Counties do not correspond well to any particular geographic birding region. Many of you may keep track of sightings within the 80-km circle centered on the Centre Street Bridge in Calgary, which is used for the annual May Species Count (and for both the 2005 and 2015 birding competitions). Here is the relevant map for that:

If anyone would like to be able to draw the 80-km circle on Google Earth on their own computer, just email me at birdscalgary@gmail.com and I will give you instructions.

Tonight, Wednesday February 8, 2017, Mike Harrison will speak at the Bird Study Group of Nature Calgary on The Ins and Outs of eBird. If you are an eBird user or want to learn about it, please come out. See this page for details.

Birding App Review – Birdlog for Android

Jul17

Posted by Dan Arndt

Note: This review is for Birdlog version 1.05. As apps mature and are upgraded to newer versions, some features may change for the better or worse, and new bugs may arise or be removed.

I’ve long been a fan of technology, and while I’ve only seriously been using eBird since January, there are so many times in the field that I had wished I’d been able to just post my exact location and what I saw there right to eBird, without having to stop, take notes, and try to remember where exactly this pond or that grove of trees was. I’ve got a bit of a talent for spotting locations using satellite or aerial photos, but remembering the exact time of day, all the assorted additional species around (and numbers), can be a bit of a task.

My wishes were granted when BirdLog was released for Android (along with iPhone, and iPad apps, if those are more your style) by Birds In The Hand LLC. Right from the App, you can find your location down to incredible precision using the GPS, which uses satellite photos from Google Maps.

From there, you can enter in the time you started your observations, and the list is sorted taxonomically, and split between the Likely birds in my area, to All reportable birds in my area, and lastly, by the birds actually seen in the report.

Every time I turn around, I am again amazed at what this thing can do. In the search bar, you can search for the bird species instead of scrolling through the list by name (Red-breasted Nuthatch), or banding code (RBNU), which saves a whole ton of time if you’re trying to record numbers in real time, while also lifting your binoculars or camera to try to get your eyes on the bird itself.

Lastly, before finalizing the list, submit the usual questions eBird uses to document the time, effort, and species data. How long it took, how the observation was made (Travelling, Stationary, or Incidental) along with distance covered, the number of observers in the party, and whether you’re listing all the birds you identified, or only a few species present. You can then choose to save it (in case you want to review it again before submitting to eBird) or just send it right there in the field, or from the pub, after you’ve stopped for your post-birding libations after recording your first ever sighting of your most recent life-bird observation.

Once you’ve submitted a checklist to eBird, if you decide you want to go back and view the list again, or make any changes to it, you’re greeted with this happy little screen, and a link to where you can edit the data on the eBird website.
