Day_Length

Taken from Forsythe et al.(1995) A model comparison for daylength as a
function of latitude and day of year. Ecological Modelling. 80: 87 - 95

Collision Risk Models for avian fauna (seabird and migratory birds) at
offshore wind farms. The base deterministic model is derived from
Band (2012) <https://tethys.pnnl.gov/publications/using-collision-risk-model-assess-bird-collision-risks-offshore-wind-farms>.
This was further expanded on by Masden (2015) <doi:10.7489/1659-1> and code
used here is heavily derived from this work with input from Dr A. Cook at the
British Trust for Ornithology. These collision risk models are useful for
marine ornithologists who are working in the offshore wind industry, particularly
in UK waters. However, many of the species included in the stochastic collision
risk models can also be found in the North Atlantic in the
United States and Canada, and could be applied there.
