The cost of migration

It has long been assumed that migration is a risky undertaking for birds, but it is challenging
to assess to what extent the risks are fatal. A recent review summarises findings from studies
of 30 migrant species, with some fascinating results.

“In general, late autumn to midwinter is one of the quieter times for rarities and this year it was exacerbated by the Covid-19 lockdown. Fortunately, later in the review period some of the restrictions were relaxed slightly and people could move a bit further afield and also more often, giving the opportunity for a few good birds to be found and reported.”
