Greetings from the shire where I have just returned after spending a few days with the folks. I managed to catch the Jilguero a few times in different locations. Hard to catch him by himself and you can hear the noise of the city and very annoying dogs. I have not deleted any files since I know you might want to hear them all and choose for yourself. There are other birds there too, including humming birds. They are the ones with a rhythmical and repetitive high pitch chirp.
