I just read the other day that new climate models show short term cooling trends buried within the general upwards climb of global temperatures.
It has to do with shifting ocean currents and their effect on rain and circulation patterns.
This spring here in the ARK certainly confirms that analysis. We have been recording the arrival of the first hummingbird for 22 years. He ( it is always a male) usually shows up between April 18th and 23rd. I remember one year, down at the “Glad Cab”, (where we lived while building our present home), being strafed several times one spring afternoon until the feeder was hung on the old hame we used for such purposes. After that we always made sure we have the feeder up and hanging by the 18th—it’s safer that way!
The first hummer is joined a couple of days later by another male, which then begins the usual aerial battles, then another male appears in the next day or two and finally, a few females come to check the summer accommodation. This sequence never varies; the process is the same each year.
But the arrival times do change. One year the first hummer arrived on April 9th, so we had to scramble to find the feeder, make the solution and put out the food. On the other end we have had arrivals as late as April 26
This year things were quote cold, with minus 7 or 8 each night and the snow and ice taking forever to disappear. We put out the feeder on the usual date and as the days went by we started to become concerned. By the 30th of April we really began to worry. Maybe the whole flock of hummingbirds that know our feeding station—the only one for many kilometers—had been wiped out.
Rosemary sent out a few emails, and yes, others had noticed late arrivals, but at least theirs were there. Each night we would bring the feeder in to stop it from freezing, and put it out early in the morning, hoping to catch the first arrival.
I was in the office on the phone about 10 in the morning on May 1st, when the first hummer flew into the window, trying to get at my red sweatshirt. What a relief to see that little guy! I alerted Rosemary, and a few minutes later she reported that he’d arrived at the feeder, drinking and drinking and drinking.
So, a late cold spring, as part of global warming, caused our hummers to be 8 days late. I wonder where they hung out for that extra week. Did they sit on the coast checking the forecast on the web? Did they sniff the oncoming winds? What did they do?
Because the very day it warmed up, was the very day the first one arrived, a little bird with a big mystery.
