On an Ordnance Survey map, a small black triangle represents a zoo. This symbol is used to denote the location of a zoo within the map area, making it easily identifiable for users. The black triangle is a standardized symbol used by Ordnance Survey to represent zoos across their maps for consistency and clarity.
The name dates back to World War II. Much of the mapping carried out during the war was done by the Department of Ordnance (the guys who take care of munitions, artillery, tanks etc.). Their maps then, were known as Ordnance Survey maps. Today, Ordnance Survey maps are carried out by civilian teams and have nothing to do with ordnance but the name has stuck.
Securing aerial maps before conducting a reconnaissance survey is essential to ensure accurate planning and navigation during the survey. It allows surveyors to identify key landmarks, potential obstacles, and specific areas of interest beforehand. Using up-to-date and precise aerial maps helps to improve the efficiency and effectiveness of the survey by providing clear guidance and reducing the risk of errors or misinterpretations.

Google Maps, Yahoo! Maps and British Ordinance Survey maps use a mid-blue colour for all water features (rivers, streams, lakes and the sea).
I wonder, which map the question originator is looking at? On Ordnance Survey maps symbol guides, there is no RED STAR. There is however a blue star meaning: Other Tourist Feature.
