Most subsequent visits have been all-too-brief transit stops en route to and from the Azores, but back in 2012 I had the opportunity to make the most of a longer airport lay-over by teaming up with João Jara of local specialists Birds and Nature Tours Portugal. A few very worthwhile hours on the Tejo Estuary produced some excellent birds on that November trip, not least Greater Flamingo, Black-winged Kite, Iberian Grey Shrike and two countable ‘Category C’ species, Black-headed Weaver and Yellow-crowned Bishop, for which the Tejo's rice fields and marshes are well known.
