Interesting facts about the Collared Dove

I don’t know the what year in the 1950s that they first bred but it’s interesting that’s the first Collared dove you saw was in the late 1950s cause it first bred in the 1950s in Norfolk.  and thats the same year  you saw one for the first time

Always interesting to read about species status.

The green amber red status you mention is a very common form of progress (and risk) assessment, often referred to as the traffic light status or RAG (red amber green) status.

It is ideal for early data collection and being straightforward in appearance, it often makes for a good portrayal of an over survey results  and simple presentations.

In my last role before retirement, one of my prime data collection processes involved compiling risk assessments and presenting the overall status to managers and engineers. The presentations were based on the RAG scheme, for quick clear and concise presentations.
