Match their hatching dates with peaks in winter moth abundances provides the most high energy food for their young. As the temp has been warming winter moth peaks have been happening earlier, the oak bud bursts are also happening earlier but not as much (out of sync) Some of the great tit have adjusted but mostly not.
