141 A cool-season Band-rumped Oceanodroma castro, Farilhão Grande, Portugal, September 2020. I had been invited to join an SPEA bird-monitoring team visiting Farilhâo Grande. Their visit, heavily weather dependent, was limited to just one or two nights. Timing was perfect as prospective breeders would be exploring potential nesting sites, just before laying the single egg. The weather allowed us to stay on the steep rock for two nights. The second night, when the activity in the colony finally died down around 06.00 hrs, my IR system had been triggered 31 times by an overflying bird. A fabulous night!
