Or, buy lots of birdseed, nuts, fruit and put it outdoors for the birds. Robins no longer migrate South and have been wintering in NJ for a number of years. They hit up our Holly Trees when the berries are ripe and the ground is covered in snow making it difficult for them to find bugs.
Most other birds will enjoy the seed as long as it's a good mix of many varieties.
Plan ahead when you are landscaping or buying plants, not just for beauty but for the bounty they provide our feathered friends and you will be able to enjoy birds year-round.
