This very unscientific research, based entirely upon casual observation, is concluding nicely, and perhaps the last phase to measure the reaction of squirrels to being shot in the hindquarters by BB’s will not be necessary. Time spent by neighborhood squirrels at our birdfeeder has steadily declined with a switch to sunflower seed treated with hot pepper sauce, and now to safflower seed, as suggested by a reader in Haymarket, a few miles up the road from here.
While banging on windows and loudly shouted threats of violence did little, the pepper treated seed was moderately effective, discouraging several regulars, and shortening the time at the feeder for the few stubborn holdouts. While a redtailed hawk (above) proved most effective, warding away squirrels, but also birds, a more complete deterrent was desired, and after several days it appears the answer could be safflower seed.
Yes, squirrels sampled the new seed, but seemingly found it undesirable, cutting short their stays at the feeder, and then not returning except one that partially dismantled the feeder in hopes that choicer seeds must be hidden within. The smaller safflower seeds tumbled from the open window of the feeder into a mound on the ground below. Now, cardinals inhabit the feeder while chickadees forage on the ground, and no squirrels have been seen on this pleasantly chilly afternoon. Somewhat curiously, no bluejays have been observed at the feeder since the change in seed, though they seem to come and go and very probably will return.
In the surrounding garden, the effects of recent mild temperatures are readily apparent, with many early snowdrops and hellebores (above) coming into bloom, and buds of hybrid witch hazels beginning to open to join the earlier flowering Vernal witch hazel (Hamamelis vernalis, below). While cooler weather is forecast, the lack of extreme cold will encourage flowering to progress.
Prospects for February are excellent. Without squirrels at the feeder, my wife will be happier, and possibly the kitchen will be more peaceful without the banging and shouting. And, the gardener will be enthused further by the increasing numbers of blooms.
