Continuing with Winter Raptors of the Tagus Estuary: This is a female Common Kestrel. European Kestrels are a size bigger than even the biggest North American Kestrels, and don’t have as much of a “dainty” look. I saw many dozen female Kestrels on the Tagus Estuary over two days there, but not a single male. Perhaps the males winter elsewhere, or there are just that many fewer males. Sony RX10iv at 600mm. Program mode. 1/250th @ ISO 250 @ f4. Processed in Photoshop Express. My two days on the Tagus Estuary were part of my tour of southern Portugal with Birds and Nature Tours Portugal.
