Seabirds

Sooty Tern The Sooty Tern is highly aerial and marine and will spend months flying at sea, returning to land only for breeding.

Seabirds are birds that have adapted to life in the marine environment. Whilst seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous, and modern seabird families emerged in the Paleogene.

Classification of the bidding systems in contract bridge

  1. Natural systems in general have the following features:
  • Level-1 suit bids denote at least 4 or 5 cards in a major suit, and 3 or 4 cards in a minor suit, with strength of about (11)12-20(22) high card points. The suit bid is generally the longest. The former criterion inflicts further classification into four-card major and five-card major systems.
  • Bid of 1NT always presents a balanced hand in a narrow high card points range. The common ranges are 15-17 or 16-18 HCP ("strong notrump") and 12-14 ("weak notrump").
  • Bid of 2♣ typically presents a very strong hand (23 HCP up).
