The traffic congestion of Celtic Tiger days is back. During that misguided era, we commandeered huge swathes of countryside and obliterated ancient sites to make way for cars.

THERE’S a ‘bring back the lynx’ lobby in Britain. Deer numbers in parts of England and Scotland have risen so much that their habitat is being seriously degraded. Excessive grazing is threatening native flora and there’s a new kid on the block; over 40,000 alien muntjac deer are destroying farmers’ crops.

CUCKOOS are arriving from Africa. Pity the poor meadow pipits they will dupe; their clutches destroyed, they will work themselves to the bone raising the enemy’s chicks.

THE Twentieth Century fox moved to the city and is prospering. Now the 21st Century rabbit is following suit. 

Birds living high in the mountains are better problem solvers and have more reliable memories than ones living lower down, according to research just published, writes Richard Collins.
