A new phase for the Atlas

With the completion of fieldwork for southern Québec (2010-2014), the Atlas project has reached an important milestone, and we would like to send our sincere thanks to the 2000 participants who between them devoted more than 100 000 hours to data collection.

Nevertheless, this does not mean that all data collection is finished, as fieldwork for the region north of 50°30' N will continue for several years to come!

In parallel, the Atlas Team will be concentrating on the publication of the results for southern Québec. We will keep you regularly informed about the progress of this part of the project, which aims to analyze and publish the data acquired between 2010 and 2014, including a comparison with the results obtained during the first Atlas.

Those of you who wish to participate in the northern component of the Atlas should, in addition to regularly visiting this website, subscribe to our mailing list to receive our newsletters. To help with planning and to avoid overlap, we would like hear from any experienced and independent birdwatchers who are intending to visit northern Québec to collect data for the Atlas.

For your information, we will be adding sections to this website containing a variety of information about the northern part of the project. However, in the meantime, you can find a range of basic information on the Northern Québec page.

Less well known than the Snowy Owl, the Great Gray Owl remains, nevertheless, one of the most remarkable winter visitors to southern Québec, and in years when small rodents are scarce in the taiga and the boreal forest, it can show up in good numbers. However, this species does not only occur in southern Québec during winter irruptions, it also breeds at our latitude. During fieldwork for the present atlas, it was recorded in about 20 survey squares, mostly in Abitibi, where nesting was confirmed. Great Gray Owls favour open areas and wetlands for hunting, but are less selective when it comes to choosing a nest site, which can be located in a mixed, spruce or aspen forest, or peatland. It does not build a nest but appropriates one built by another species, usually that of a hawk or a Common Raven. Occasionally, it also nests at the top of a snag or on the ground. The female alone incubates and broods the young. The latter leave the nest at between three and four weeks of age. They remain dependent on both parents for some time, after which the male, alone, takes over. Active mainly at dusk and during the night, this species is far from timid and, with the exception of the Great Horned Owl, has few predators(adapted from Gauthier and Aubry 1996).

The Québec Breeding Bird Atlas project is open to birdwatchers of all skill levels, and we strongly encourage you to get involved. The aim of participants of the Atlas is to find breeding evidence for as many bird species as possible within each 100 km2 survey square.
