Hi all,
    I finished cleaning out my swallow boxes today and the results from 201=
7 were down substantially.  I have 30 boxes that I've maintained for a numb=
er of years and 2017 produced only 9 boxes containing nests with breeding e=
vidence - down from 15 in 2016. This drop was somewhat expected as swallow =
activity in general last year seemed low.
     On the positive side there was a large increase in the number of flyin=
g squirrel nests; 8 full and partial, which was surprising as I had none in=
 2016. Two of the flying squirrel nests had adults and one no adult but at =
least one baby squirrel (I'm not sure what baby squirrels are called) but n=
o adult. All nests were composed of grasses (normal) and some kind of fibro=
us material like blown in insulation which I haven't seen used here by flyi=
ng squirrels. No idea where it originated. All the flying squirrel nests we=
re in one general area which was also odd. I don't know if this increased f=
lying squirrel activity is local or has been noted in other places in the p=
rovince.
    Two boxes were blown down over the winter and one of those was used by =
mice/voles. About two-thirds of the boxes had entrance holes enlarged by sq=
uirrels and will have to have the doors replaced.
    Here are the 2017 results:
9 tree swallow nests with breeding evidence
5 partial swallow nests (1 had a empty flying squirrel nest on top of a par=
tial swallow nest)
2 empty red squirrel nests
3 active flying squirrel nests (2 with adults and maybe young and 1 with at=
 least 1 young squirrel but no adult)
3 empty flying squirrel nests (1 was on top of partial swallow nest - see p=
artial swallow nests above)
2 partial flying squirrel nests
7 empty boxes
    All the best.
                     Fritz
