Why were birds missing from backyards during the super bloom?

Suzanne Mulcahy of Laguna Niguel became concerned when the hummingbirds in her yard disappeared around mid-April.

“I’ve always kept four feeders filled all the time,” she said. “There were birds at them continually. Then all of a sudden, my hummies (sic) were gone.”

Other bird enthusiasts had similar experiences with feathered friends disappearing from backyards when the spring season began blooming.
