Can Robins build nests WITHOUT mud if mud isn available?
Robins tend to select nesting territories where worms are available. The right habitat usually provides both mud for nest making and a supply of food. During periods of too much rain or not enough rain, robins will delay nest-building. Q: My Robins came back too early and has been singing. There is still snow on the ground. Is this normal? A: Robins usually return when the average day-night temperature is 37 degrees Fahrenheit. This is the average; some days will be warmer, some colder than that. And when a male arrives and finds a good territory, he can’t help but sing. Sometimes after a male starts defending a territory a sudden bad weather system will send him off to a robin flock eating fruit. But when he can find enough food on his territory again, he’ll be back. Singing is evidence that he’s got plenty of food in your yard and is ready for spring, even if the snow makes it look like winter.
