Sure, why not? But rather than focusing on a t-rex-style predatory super-bird, which would be limited by the maximum size and abundance of its prey due to its obligate carnivorous lifestyle, your best bet, IMHO, would be some alternate/future evolution relative/descendant of the Hoatzin: the last surviving member of an order of birds which recent genetic ...

Many other birds, especially seabirds and also swallows, are known to have equal or better homing abilities. A Manx shearwater (Puffinus puffinus), transported in a closed container to a ...

Storks -- they are migratory and thus have good navigation, they are large enough to carry decent sized messages, they have some interesting colors ...and - as everyone knows - they already deliver babies.
