--=_0825e335012ed6e100446dbfeaf50701 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=UTF-8 I didn't realize rbnh's were migratory, and I've had several nest in my bird boxes in the past. This would explain why I didn't have any all summer, and recently a pair showed up and are helping to put a dent in the black oil population.

The annual seed crop of conifers is cyclical and as a result, Red-breasted Nuthatches cyclically irrupt south from their Boreal Forest haunts in years when the seed crop is poor. Many of the species that nest in the Boreal Forest are also found in the Maritime Forest and the birds you're seeing in summer are obviously breeding locally. However many of the birds that you see in the winter in the province may originate from New Brunswick and points north. There was a good movement of Red-breasted Nuthatches on Brier Island at the end of August indicating that the conifer seed crop (basically white spruce) in the region was probably not that good this year and local Red-breasted Nuthatches are heading south. > > As an aside, many finch species similarly move south from the Boreal Forest in poor seed crop years. Ron Pittaway's Winter Finch Forecast for this year is an annual prediction of which finch species (and some others such as Red-breasted Nuthathces) will be moving into southern Canada and which won't.

I kept looking up at the big pine about ten feet to my southeast and the little guy showed himself cavorting around the trunk. First white-breasted nuthatch I have seen down here for over fifty years. On considerably more occasional visits on the Hamilton road, which runs between Pleasant Valley and Raynardton, I have seen these guys two or three times over the past couple of decades. > > That reminds me: In recent decades, red-breasted nuthatches have been fairly common in our neighbourhood. I have neither seen nor heard any this summer, and cannot recall any reports from anyone of sightings. Wonder how those little guys are doing, globally.
