I'm not certain of this, but it seems both the Minnesota and the
Ontario kingbirds may be on molt cycles reflecting an Austral rather
than a Boreal breeding and migrating populations. The Minnesota bird
is completing a molt and I thought that the Ontario bird may still
have juvenile outer rectrices and outer primary (but not worn enough
to be a year old). Better photos of each, with open wings and tails,
would help determine molt progression and age. For northern Tropical
Kingbirds (occidentalis) we would expect to see molt patterns like
this in Nov-Dec on the winter grounds (both preformative and
prebasic) and not June. Something to consider when encountering and
documenting summer kingbirds in North America.

Hey everyone-
I went out to chase the Tropical Kingbird that has been seen at
Murphy-Hanrahan Park south of Minneapolis/St. Paul and got a few
photos that I have posted here:

The bird was seen off and on between about 7 am and 9:30 am. It
did not vocalize while I was there.
