What species are these Florida birds?
My sister snapped this pic of birds that were going through her Florida neighborhood (just west of Orlando) during the winter of 2018. I believe the two at the left are adults, while the rest are fledglings. I tried to find them on the web and in my print bird guides, but, only got matches/opinions based on shape (ibis or heron), not the colors, which don't seem to match any breed. Any help would be appreciated. It would be great, if you could include a link to a definitive web page with image and description. Thanks!
