The more buds you spot on the ends of small limbs the more likely these limbs are the ones to keep on your property if you want plenty of song birds to be in your neighborhood when spring comes. You might also try to convince your neighbors to preserve some similar brushpiles on their property. And urging neighbors to preserve ice-damaged trees on their property also will help.
Many won't understand. But every property owner who keeps a brush pile or resists pressure to cut down a damaged tree can make a difference in the reproductive success of song birds in the coming spring.
