As a birder, I’ve found this place to be a complete treasure trove for many species difficult to see elsewhere. Personally I’ve seen over a hundred species over several birding trips there, the overall species list for the location is approximately 160 – a tally that will only increase.

A quite uncommon bird – there are only about 6000 pairs on the planet and this is one of only a handful of my observations of this species. Two-thirds of the world’s population breeds colonially on Greek islands. My first one was about 20 years ago not far from Thessaloniki, three dark morph birds, and I still remember it.

In recent years Indonesia has been competing with the Andes as the region giving rise to the biggest number of undescribed bird species (naturally, all of them endemics).

Wood Sandpipers- Tringa glareola are a shorebird species that are found on inland fresh water rather than along the coast. Wood Sandpipers can be very aggressive to others of the same species and it is not unusual to see a pair face off at each other and then fly up at each other to defend a feeding area.

The only way that the birder can tell they’re affected by the wind is by comparison with how they flew yesterday — the arcs are a little shorter, a little shallower, before they return to the underside of the bridge.

One of Britain’s recent colonisers the Mediterranean Gull begins to arrive in bigger numbers every year as post-breeding dispersal takes hold. In fact I would go so far as to say it is probably the best site to see the species for 100 miles in any direction and best of all it’s only 4 miles as the gull flies from where I live.

Most likely, all individuals of a given species have very similar genes guiding very similar developmental processes, but produce different results because the plasticity itself is selected for. But, if you capture wild birds (to make them pets) then breed them through one generation and they get out, they are bad at avoiding predators.

Major extinction events that are geologically instantaneous have been followed by periods of time with reduction of species or unstable habitats that last for hundreds of thousands or millions of years. There are about 10,000 species of them, after all, which is a lot for a vertebrate. But, that is also a naive view.
