Great plants, and your animals a a delight to view.beefy said:yes, those are cattle egrets.
ive never tried letting coleus seed out. i just bought one or two of each color earlier in the year and rooted all the others from those. i sort of placed the colors to compliment each other but not really. i mostly just planted them wherever there was a spot available whenever i had rootings ready for soil. a lot of them i just stuck directly in the dirt and let them root there. i actually got the orange one dead on a clearance rack for 25 cents and revived it rooted a lot of them from that plant. got the caladiums on clearance too latespring.
