--=====================_4934953==.ALT Content-Type: text/plain; charset="us-ascii"; format=flowed An astute observation, and I agree with you. The first time I saw wintering Baltimore Orioles in my neighbourhood, they were in this tree, at twilight. That was the winter when you and my neighbour kept - was it 7? - alive through to April. I spoke to another neighbour today, and the tree was reportedly a west coast species, the Nootka False-cypress, that is Callitropsis nootkatensis formerly Chamaecyparis nootkatensis, aka Pacific Coast Yellow Cedar. Those who live in more expansive suburban or rural areas may be amused by our attachment to a single tree, but believe me, in the close confines of the city, one well-chosen tree can make a difference.
