Thanks all for the positive comments. We like to set the bar high for our tables...

I will try to get some closeups posted on the animals soon.
Off the top of my head:
Ostriches - metal Irregular Miniatures (both 25 and 15mm scales)
Cape Buffaloes, Rhinos - Plastic toys from Hobby Lobby (mojo minis)
Leopard - plastic toy
Oryx, Hyenas, Wildebeest, Jackals, Buffaloes - metal Iron Wind / Ral Partha
Giraffes - small ones are plastic toys, two large are ceramic models culled from an african-themed candle holder (two giraffe grazing on an acacia tree) found at a thrift shop
Kong - resin Acheson Creations 28mm
Funts - plastic Scheich/Safari World
I have a menagerie in the works to include:
vultures (flying and on ground)
hippos (on land and semi-submerged)
crocs (same)
zebras
lions
cheetahs
meerkats
gorillas
warthogs
would love to source some more herding types - topi, gazelles, kudu, hartebeest, etc.
