See our state by state hummingbird migration table listing the average arrival dates. So this gives us hope that these very adaptable little creatures will have the capability to adapt and survive changing conditions. Studies have shown that hummingbirds have the sense to alter their routes according to the resources available. However, 300 miles or so east or west of their usual migration route there may be flowers ready to fuel their needs. Some years flowers will be in bloom when hummingbirds are passing through and another year they might not be blooming. Weather conditions will vary from year to year which affect when flowers will bloom in a particular area. They have the ability to alter their migration routes according to the flowers that are in bloom. If temps are generally getting warmer, flowers maybe blooming earlier resulting in flowers that are past bloom when hummingbirds arrive in the area Hummingbirds need the nectar from blooming flowers to fuel their long journey. Some studies/opinions hint that it could be a problem if hummingbirds arrive in a certain location expecting nectar but the plants are done flowering when they arrive. How does climate change affect the Hummingbird Migration? Some will spend the Winter along the western coast of North America. However, not all hummingbirds migrate each year. This usually starts in late August into September. The Fall migration south back to Mexico and Central America starts when the abundance of insects (their main food source) starts to dwindle with cold temps. They will double their body mass in weight to “fuel-up” for the long journey. Males will usually migrate first followed by the females about 10 to 14 days later. Some scientists believe that they will also stop at the same feeders along their route on the same day every year during their migration journey. It is believed that hummingbirds will return year after year to the same feeders where they wore born. But it's a demanding trip for the unprepared.The Spring migration for the Ruby-throated hummingbird usually starts in February and ends in late May in their northern most habitat of Canada. Steve Coleman listeners who have become admirers of Shyu may be fascinated by these uncompromising virtuoso dialogues, as might any student of contemporary improv-vocal technique. Dresser, who is a precise, resoundingly emphatic bassist with a composer's sense of shape, provides low-end contrasts to his partner's vaporous musings – sometimes stalking her movements, sometimes furnishing driving basslines, jazzy fast walks or fiercely abstract bowings like the work of the UK's Barry Guy. She blends fragile, light sounds with dark, low notes, ruminative hummings and improv in a personal language that fuses English, Taiwanese, Mandarin and several others. Shyu is a remarkable phenomenon, shifting registers with startling ease and tonal resourcefulness, moving from conventional pitching to a yodel-like ambiguity without fuss. That was a group exercise, but Shyu (who has worked with Coleman for eight years and in her Jade Tongue band with New York saxist David Binney for three) makes much more intimate music here – in a duo with former Anthony Braxton bassist Mark Dresser. J en Shyu, the Illinois-born cross-genre vocalist of East Timorese and Taiwanese descent, recently made a formidable contribution to saxophonist Steve Coleman's latest album, The Mancy of Sound.
