I'll do my best!! Other than size (Spark is smaller) look for the right band. Durand's is silver, Spark's is dark purple. Durand has more white above her beak. Spark Squeaks~his vocals are higher pitched. If a bird is sitting near the ledge cam (and you're not sure who it is) watch its behavior if it goes to the box. 99% of the time, Durand jumps to the lower ledge, then goes to the box. Rarely does she travel the length of the upper ledge on her way to the box. (If I ever see her travel the upper ledge to the box, I always pay close attention once she enters the box. Even if she lands mid ledge, she will often hop to the lower ledge before going to the box..She so rarely uses the upper ledge, that it always sends up a red flag for me if she does..) Spark, on the other hand, usually hop/flaps or flies from the ledge cam end to the box end~always along the upper ledge. I rarely know who I am looking at if they are sitting on the box end..unless he/she vocalizes..if I hear high pitch? its Spark..lower pitched echups, its Durand (sometimes she sounds like a honking goose)..
If you can see the left bands, then Durand is 32/X and Spark is b/r 32/B. (I always found it interesting that they both have "32" in the band #'s!!
I know there are other differences, but will have to put my thinking cap on..
thank you SGB, this is very helpful - I see that Mike has posted a picture of either Spark or Durand on the LeVeque - great picture - no bands showing so it's hard to tell who it is especially not being able to compare sizes
