March is coming to an end. Some early migrants have already arrived. The next few months bring the excitement of waves of migrants heading to their breeding grounds and others establishing their territories locally. If you started a year list, or just want to learn where and what you might see in the OFNC study area, here’s a reminder of an excellent reference prepared by Greg Zbitnew. Check it out at Finding 250 Species – Part 2 ..read more

On Monday March 4, astronomer and repeat presenter Howard Simkover delivered a special presentation to the OFNC via Zoom on solar eclipses. This is particularly timely as a total solar eclipse will occur on April 8, 2024, across a swath of North America. Locations not too far from Ottawa in Southeastern Ontario will find themselves in the zone of totality.
Howard’s presentations are consistently excellent, and his reputation preceded him – so much so that the Zoom presentation was full, and some people were unable to join live. Happily, the presentation is now available on the OFNC YouTube cha ..read more

Thanks to the continuing efforts by Greg Zbitnew, excellent study documents were updated and are now available on the website. The first is an annotated checklist of all birds in the OFNC study area and the second is an annotated checklist of rare birds in the same area. Given the rarities that have been appearing in the past year, these are especially interesting documents.
They are available at Ottawa Annotated Checklist of All Birds -December 2023 and Ottawa Annotated Checklist of Rare Birds December 2023

The 105th Ottawa-Gatineau CBC was held December 17, 2023. Temperatures ranged from minus 1.5 to plus 4.5 degrees Celsius, with cloudy skies throughout the day. Except for one cold snap, temperatures were mild leading up to the count; however, with the rivers being so open, water birds weren’t all forced into the count circle area as is the case in most years.
161 field observers plus 32 feeder watchers found 77 species and a record high 54,598 individual birds. Highlights included a first record for Western Tanager, a second record for Wood Thrush, and a fifth record for Red-shouldered Hawk. O ..read more

The impacts of warming temperatures on the diet quality of Monarch butterflies and what we can do to help
By Katherine Peel, with great thanks to Dr. Heather Kharouba, Jenna Boomhower, and Dr. Greg Mitchell for their work on the project

The project was inspired by the significant decline in the size of the eastern migratory Monarch butter ..read more

Started in 1900, the Christmas Bird Count (CBC) is North America’s longest-running Citizen Science project. People in more than 2000 locations throughout the Western Hemisphere participate in the CBC each year. There are lots of opportunities to volunteer to participate in this exciting project, meet new people and even learn more about other birding areas. You are not alone. Most counts organize small groups of people to cover defined areas so you do not have to be an expert birder.
Three OFNC supported counts are:
ONRI – Richmond-Munster-Manotick Count December 16, 2023. Co ..read more
