From a trip report on a day in Lisbon on a cruise:
The authorities have planted scores of trees by the cruise terminal just below the old part of Lisbon. A Chiffchaff was there, singing briefly. The tide was low early morning and as we headed to the Cais de Sodre ferry terminal there were some Sanderling, a Grey Heron and six Ruddy Turnstone on the edge of the Tagus. There were a further twenty Sanderling by the ferry terminal. Some Lesser Black-backed, Gull, Black-headed Gull, Yellow-legged Gull and Mediterranean Gull were seen too. We passed a small pond and thirty Barn Swallow were hovering above it.
We took the ferry to Cachilas and on the other side there was a flock of Sandwich Tern, three Cormorant, and a Mallard. We walked west from the Calchilas terminal along the dilapidated sea front. Two Black Redstart were seen. When we reached the small park area we then headed up the steep road to the top of the lift, there were several Serin, Greenfinch, Goldfinch, Blackbird, Collared Dove and a Barn Swallow. After that we went to the imposing statue of Christ the King where they had established a large area of lawns, trees and shrubs. Two more Black Redstart were seen as well as a lot of Goldfinch, a few Serin,Blackcap, House Sparrow, Greenfinch, Chaffinch,and Blackbird. A Chiffchaff was seen feeding. There's a regular bus service from Cachilas to the statue of Christ the King.
There's also a ferry to Montijo from the Cais de Sodre ferry terminal which might be worth a ride to see what birds are about on the River Tagus.
We sailed out of Lisbon at 4.30 pm. It is worth taking up a position on the port side as you soon reach the open sea and obtain great views down the west coast of Portugal. Just before we sailed four Sandwich Tern arrived and started diving near the ship. As we sailed out I counted 46 Northern Gannet, two Great Skua close in, some Cormorant and a few Lesser Black Backed Gull.
