It's a sad day here. Some baby-bird-predator got the robins. I am guessing that it was a hawk or an owl based on the condition of the nest. When my husband and I got married I made it very clear that his only job as my husband (you know, except for the 'til death do us part stuff) was that he would deal with all dead animals that came into our life. Thankfully he has fulfilled that promise, because I was too sad about those babies to clean up yesterday.
