After two long weeks of parent-teacher conferences and a worn out typhoon bearing down on the Bay Area, I had a surprise as I drove up Moraga Street, one block from my home. I took a different route home because of some road work. And as I was heading up the hill, I saw a bird on a wire.
Any bird on a wire that looks a little “off” is bound to catch my attention and this bird did. At first it looked like a really light colored scrub-jay. But as I moved closer I knew it could only be one bird.
The bird’s location in the middle of the wire, it’s bright yellow breast, and its menacing ever vigilant gaze signaled that this was a tyrant flycatcher. And it’s brown, notched tail and heavy, violent bill, seen through by car binos, confirmed that it was the rare but regular visitor to the west coast, the tropical kingbird, Tyrannus melancholicus.
This is an apt name for the genus that shares part of it’s name with the tyrant lizard king, Tyrannosaurus rex. The tyrant moniker is given to the genus of kingbirds (another link with T. rex) because of the aggressive nature of these flycatchers, especially directed towards much larger birds (hawks, eagles and falcons) during the breeding season. The tropical kingbird’s species name, melancholicus, comes from Greek, meaning of a melancholic temperament. The Greeks believed that one was guided by the four humors (blood, yellow bile, black bile, and phlegm) and if you were out of balance, in this case by being over loaded with sullenness or violent anger, then it would contol your demeanor (by being full of black bile). That’s the long way of saying that the tropical kingbird gets really pissed when intruders are in it’s breeding territory.

I watched the kingbird sally forth from it’s wire perch returning each time with a flying insect in it’s beak. On one such attack, the yellow-breasted tyrant launched itself 60 feet into the air, returning with a yellow butterfly, which the hawker dispatched in two deft gulps. The bird worked it’s way up and down the power wires of Moraga Street, eating as it went.
On my after dinner stroll, as the harbingers of our first winter storm filled the sky, there was the kingbird, taking the highest perch. It sat, resting from it’s travels and it’s high energy aerial hunts, where it now sang, to no kingbird that was anywhere near.
