Help! This evening when I got home at about dusk there were at least 15 or more ROBINS flitting around and sitting on my fence all puffed up against the cold. They looked a little frantic because most of the ground is snow covered. They seemed to be looking in my neighbors brick planters that are up against the house and where the snow has melted. NEVER have I seen robins here is the winter. I am wondering why they are here... But more importantly, I am wondering what to put out for them. I know in summer they eat worms and bugs... I've been putting out seeds, fruit, peanuts, and crackers which the other birds and squirrels are making use of... but not the robins. I'm not at all well informed about birds... Please, advise, so I can offer the poor things some sustenance. Thanks!
