Swallows have MTU issues.

I was wondering which April 1st this would happen on.   Now I know.  So
if a v6 carrier swallows a v4 datagram does that count as packet loss or
tunneling?

I was disappointed in this RFC -- Section 3.1 didn't include the proper
discussion of the difference between African and European avian carriers,
and we know what happens if that question is asked at the wrong time.

That applies to swallows. I'm not sure pidgeons pose the same issue. I
think in general, swallows
provide poor platforms for avian transport of IP datagrams.
