We are all watching to see if a nesting season materializes in the nest this year. In past years we have seen eggs in the next week, with a good deal of presence in the nest during the second half of January.
We suspect that the lack of time spent on the nest could indicate that our pair has another nest, a normal occurrence after using a single nest for this many years. The cold weather could also be an impact, slowing things down a bit.
Time will tell, and I will keep you posted.
