Dendrobium loddigesii is a well known orchid. Here in Brazil it grows well and requires absolutely no care.
But, look at who decided to set family in the pot!! Three hungry mouths are always waiting for bugs that their parents bring from early in the morning until late in the afternoon! This is the Tico-tico (Zonotrichia capensis), a well-known bird here.
The second and third photos show the diligent mother (I presume! based on the vigorous way she protects her babies, you know, mother stuff!!)
