Mystery shrouds loss of migrant birds

Turtle doves, spotted flycatcher, wheatear and the wood warbler used to migrate between Europe and Africa every spring. Why don't they come around anymore?

Scientists fear that their dwindling numbers - well over 50 per cent down in some cases - may be a warning of widespread environmental damage, which could soon affect man as well.

Scientists theorizes that climate change,
drought, desertification and pest control are all causes for the loss of migrating birds.

The study of 121 different birds in the period 1970 - 2000 shows a worrying decline, or total loss of visits to the european continent.

poor little birds

besides obvious habitat changes due to climate, I'm wondering if there if bird flu would also be a contributing factor to their decline in numbers? Or is it that they have just somewhere else more suitable to return to and nest?

Good catch, Vaak.

This is more bad news from the avian front.
