Study: Hummingbirds migrating earlier in spring
Associated Press ^ | Feb 17, 2013 2:10 PM EST | Bruce Smith

Ruby-throated hummingbirds are migrating to North America weeks earlier than in decades past, and research indicates that higher temperatures in their winter habitat may be the reason.

Researchers say the early arrival could mean less food at nesting time for the tiny birds that feed on insect pests, help pollinate flowers and are popular with birdwatchers. …

Jason Courtier of Taylor University said the historical data on hummingbirds is based on government surveys from about 3,000 naturalists around the country who recorded the first spring arrival time of bird species over the decades. About 6 million such records exist and are being scanned into computer databases by the North American Bird Phenology Program.

The research compared the historical documents with about 30,000 recent records on hummingbird arrivals. Scientists say the earlier arrival times could be problematic for hummingbirds, of which there are an estimated 7 million. …

I think this whole thing is for the birds...

I’ve noticed it but it depends on the season that year. It’s not consistent.

I live just north of Charleston, SC. I usually see them in late March-early April. I fill my feeders early so that I know that they have arrived.

They are fun to watch around the feeders. They use their beaks as fencing swords if they don’t feel like sharing the nectar from a particular feeder. They will feed and then fly to a high branch in a tree, wait for another one to come along then fly down and defend the feeder. A window feeder is essential.

This is essentially anecdotal evidence. My bet is that there are lot more people logging observations than there were in the past, yet the old observations and the new observations are weighted the same.

Absolutely correct!

If the birds fly away from where it is too warm, fly past where it is just right, and end up where it is too cold to survive, then they deserve the Darwin award they are going to get.

Or maybe it is the scientists who deserve the dunce cap for speculating from too little information. The birds are adapting to variation in the pattern of seasons. Likely some always overshoot to try to be the first to grab the best spots for the summer.

Tempertures don’t have a dang thing to do with it. Hummingbirds are just like everyone else. They have to cut their vacations short due to running out of money. It’s the economy.

Sometimes we have so many it looks like a swarm of bees- at lease 50+ at a time. I have three feeders and make my own hummingbird foodt - 4 parts of water to one part of sugar, bring to a boil for a couple of minutes and let cool. I go through about 5 lbs of sugar a week in late spring and taper down starting in September through the middle of October.

Yeah...cuz it doesn't get any warmer for the bugs. Asshats. We have species that winter over(Oregon Coast) and do just fine on insects in the winter. The hummers are starting to pick through the spider webs on the windows...nesting materials, and guess what...spiders and their prey.

I have observed and recorded the arrival and departure dates of hummingbirds in my yard for the past 13 years.

It's always almost to the day the same; April 22 in the Spring; leave Sept 22 in the fall.

Thanks. I took them a couple of years ago while going through my bird photo stage. Here are a few more that I am proud of (some for the photos, some for the rarity of the bird)for your enjoyment:

Love the pics, we have many eagles and hawks around but they do not want to pose for a pic.

Makes sense. Actual research, not this kind of uncontrolled garbage, has shown that birds a) migrate according to the length of daylight, not passing weather, and b) seem to have a wired in annual periodicity which causes agitation and orientation toward the usual direction of migration at certain time frames in the year, even in caged birds in controlled environments.

The supposition that "climate change" drives alterations in these instinctive patterns makes no scientific sense. Political sense yes--students of bird behavior need grant money too you know. Might as well get on the bandwagon.

Ever seen them take on a Bumblebee? Hilarious!

Haven’t been so lucky, no.

And if I do ever see a praying mantis on the feeder, off he goes. They like to eat hummingbirds. (Sightings of the mantis keep getting rarer and rarer, speaking of that. I remember back in the 1980s that I’d see at least two or three during the summer.)
