Magnolia Warbler food item

[DAVID A LEATHERMAN]

I checked an eBird checklist by JoAnne Potter Riggle today that showed a Magnolia Warbler at Gypsum Ponds in Eagle, CO.  Interestingly several of her 20 images attached to the checklist show the bird with a captured green and white patterned caterpillar.  I am pretty sure this caterpillar is that of a Juniper Hairstreak butterfly (Callophrys gryneus). Very cool.  I hope Joann checks COBIRDS.  I do not have her email.

Below are images of a Juniper Hairstreak caterpillar by Pat Ciesla of Fort Collins via the BugWood photo archive, and the butterfly, one of our loveliest IMO, taken by me near Stoneham in Weld County.
