Abandon Nest

It's been 2 days since I last checked on the nest (when I took a picture of the eggs) and it seems mom is no longer sitting at the nest :( It has been a cold and rainy 2 days so I think any time off the eggs would be detrimental and since she hasn't been there any of the times I've checked today I can assume she has moved on. I don't understand why she would leave and I can only hope it wasn't because I climbed up there to take a picture. I did it quick and then high-tailed it out of there so she would be left alone. I guess I will not ever know why. Now, I'm not sure what to do with the eggs or nest so for now I will leave it be and see what happens.
