Winter Birding

Welcome to OFO’s Winter Birding Challenge!

After the success of our very first Birding at Home Challenge this past spring, OFO is excited to announce a new challenge, the Winter Birding Challenge, running from December 1st to February 28! Get outside to enjoy the winter; find some great birds; contribute to community science through eBird; and have a chance to win some great prizes!

The Winter Birding Challenge will focus on birding your 5MR (5 mile radius) of your home. How many different species can you find this winter within your radius? You can help reduce your ecological footprint by birding close to home and you will find some new and fun places to bird.

OFO Statement on Birding and Safety

Recent reports of sexual assault and harassment have come to light in the greater birding community. We at OFO stand with survivors and are committed to uplifting those that speak truth to harm. OFO is committed to making safety a priority for all participants in its activities and recognizes that we must work with members, trip leaders, and the birding community to ensure safety. We are reviewing trip protocols and identifying what measures are needed to keep people as safe as possible, such as creating a code of conduct which aligns with safety policies and practices to be upheld. We believe that birding, and the outdoors in general, should be a safe space for everyone, not only safe from sexual assault and harassment, but from all forms of harmful behaviour.

Atlas-3: Finding Breeding Birds in the Winter

How to find breeding crossbills

Crossbills are ranging accross the province in search of good supplies of food, in particular White Spruce cones. Crossbills will breed during the winter when food is plentiful. This is the year to search for breeding crossbills and record your sightings for the atlas. Mark Peck has written a great article about finding these birds, which is posted on the atlas website at: Crossbill Article.

Can you find a nest this year?

Announcing OFO's Birding Buddies

Birding Buddies

We are excited to introduce OFO Birding Buddies! Do you ever travel to parts of the province that you are not familiar with and wish that you could talk to local birders to get their advice on how to bird the area? Or even better, find someone local to go birding with?

OFO Birding Buddies will provide you with contact info for OFO members across Ontario who are willing to provide you with that advice or take you out birding. When you join or renew your OFO membership this year, you'll have the option being a part of OFO Birding Buddies by providing your general location, contact info, and a short description of the assistance you're able to provide for other OFO members that are visiting your area.
