Went shopping in Vasco da Gama centre and then walked by the water and ate some snacks (naughty - sorry) - but, presumably cos numbers are so depleted, the gulls went mental, it was like that Hitchcock film...
I particularly enjoyed the way this guy sat on the railing and then every time we looked away he moved closer like those things out of Doctor Who
Then it just went into a free for all and one snatched some salmon from V's hand
Driving back noticed how many gulls there are further and further from the river, I think just scavenging into towns in desperation. Maybe.
