Nice shot. Looks like a warbler nest(?). That big brown egg is a Brown-headed Cowbird egg. This species parasitises other species' nests instead of building a nest of their own. The host bird will also hatch and feed the young cowbird. Quite a sight to see a little warbler feeding a big cowbird young.
Cowbirds are partially attributed to some songbird species' decline as usually the cowbird eggs hatches sooner than the other bird's eggs and/or the young cowbird out-competes the host bird's young.

Might well be a warbler as i saw some myrtle warblers in that area myself, a few weeks ago . thanks for the ID , I'll pass it on to the club treaders., i've heard of parasitic nesters but never seen one.
