Hi Jim & All, Oct 18, 2010
Because my question 'what may have caused it ?' has had no takers I will take a stab at it.
Last winter was fairly moderate here and perhaps there was greater winter survival of squirrels, especially better survival of squirrels in good condition.
In addition, (drawing on memory) over the period spanned by late Jan (or early Feb ?) 2009 to Apr 2009 there was, in the areas I frequent, a record amount of ice at the soil/snow interface as opposed to the typical condition of no ice and temperatures just above zero C [a consequence of light snow cover in Jan when it was windy and cold].
Where this applied, I think the forest small rodent population was very reduced (based on North Alton). I think I remarked on the lack of mouse trails, and Randy replied that there were lots in his area, but can not locate the posts. Toward the end of the winter ATV (?) news noted that sales of driveway salt in NS was 3 (?) times normal suggesting that the unusual ice condition was relatively widespread.
I continue to wonder if a low small woodland rodent population may have decreased forest owl numbers in some areas in summer 2009 and perhaps even carried forward into 2010. Which finally leads to the question. Was there any indication of such decreases in the 2009 & 2010 owl surveys ?
Conceivably, a lower forest owl population might lead to a tempoprary spike in Squirrels.
On a perhaps related note, there were only 2 mouse nests in five cord of wood, when I hauled this summer from the NA woodlot, and no snakes or snake skins.
Yt, Dave Webster, Kentville

Subject: [NatureNS] re abundance of red squirrels & habits
Regarding Dave Webster's note on current abundance of red squirrels, I think it was only a year ago? or perhaps a bit longer ago that many of us were wondering where all the squirrels had gone! And, of course, fluctuations including big ones provide a lot of fodder for speculation for us.
Cheers from Jim in Wolfville

Here in L. Sackville we have had many Red Squirrels this summer. We still have a few, but Don has live-trapped and transported 8 from our yard. We began this when the Robin's nest under the grapevine over our deck was preyed upon, and the female Robin injured by a squirrel. Very cute, but can be nasty!

Subject: [NatureNS] Year of the Squirrel
Dear All, Oct 17, 2010
In the areas I frequent, Kentville yard & vicinity, North Alton woodlot
and Cambridge woodlot, Red Squirrels have been unusually numerous by a wide
margin since at least early summer.
I am wondering if this spike is widespread or localized and, in either
case, what may ave caused it.
Yt, Dave Webster, Kentville
