We are visited by goldfinches, sometimes as many as 40 on our four Nyjer feeders, from early fall into late spring. 

Last week they disappeared after the May 10 storm. Not a one has visited since then. Do they migrate North to breed around this time?

 

Any advice would be appreciated.

 
I responded that the goldfinches may have left because of a local outside cat or nesting accipiter (because goldfinches breed here, just later in the season than most birds).
