Nest Building and Courtship are in Full Swing

Our little wire suet box that we have stuffed with raw cotton and cat hair is being attacked daily. There's definite signs that "something" is pulling out bits of both cotton and hair to add to the teeny tiny nests that are being built in the area. This material, along with plant parts and spider web to hold it all together, go into the nest, which is usually located in the fork of a downward sloping branch. The tiny nest is about the size of half a walnut. She will cover the outside with bits of gray-green lichen to camouflage it, and line the inside with soft plant down,

We're seeing some mating displays as well. The mating process is quite complex involving several activities in which the female plays an active role. Males attempt to attract females' attention with spectacular courtship flights in which a male flies upward 15m or more and then dives down at top speed, pulling up at the last moment to complete a U-shaped pattern; the pattern is usually repeated several times before the male takes a break. The sound of the male's wings are particularly loud in courtship flight, which may be accompanied by vocal chittering. Eventually, the female selects a male--perhaps one with a particularly energetic display or the one defending a feeding territory that appears especially rich--and mates with him.

After the male mates with the first female, he may mate again with several others. This promiscuous "harem system" works well for the species because there are fewer adult males than females in a typical local population. After mating takes place, the female assumes all parental duties. The male does not help at all in looking after the eggs or their offspring.

Since every bird is on an individual schedule, and a lot of energy is currently being expended, there is heavy feeding activity - especially during a cool rain. The video above was taken yesterday, just about dusk and during a light drizzle/mist. Once Mom lays her two white tiny pea-size eggs, she will visit the feeders less often, as she sits on the nest for 50-55 minutes of each hour. After the eggs hatch, generally 14-16 days, she will feed the chicks a regurgitated slurry of protein (from tiny insects she eats) along with nectar and pollen. Newly hatched hummingbirds are naked and blind. By the third day after hatch, the chicks have doubled their mass, which doubles again by day five and again by day eight--about the time when the young start producing their first noticeable pinfeathers. Chicks are in the nest for almost three weeks--making the total elapsed time from egg-laying to fledging about 5-6 weeks. When the nestlings finally leave the nest, they are completely grown and innately able to begin foraging on their own.

Several pairs of orioles, both Baltimore and orchard, are hitting the jelly feeders daily. They are extremely camera-shy, however, and take off when we try to get pix.

We're working on sending out wholesale orders. This week the Owl House in Saugatuck, MI, received their order, and next week Stewart's Village Gallery in Waxhaw, NC, will have their order. We're also be giving a presentation about hummingbirds at the Lake Bloomers Garden Club next week. Our next show will be at the Green Bay Botanical Garden in Wisconsin the first weekend in June.

Hummingbird fact for today: Occasionally, because of cold, wet weather that kills the eggs or nestlings, or when windy storms blow down a nest, the female Ruby-throated Hummingbird will start the nesting process over again. If she returned from the wintering grounds early enough and linked up quickly with a male, she probably has no problem pulling off a re-nesting attempt, but if she got a late start on her first nest she may not have time to try again--especially in the northern United States and southern Canada where the nesting season is especially short.

Another Success Story

We LOVE to hear from customers, especially when they and their hummers are enjoying our feeders. We got a really neat note from a customer yesterday. He bought this feeder in 2009 at the Omaha Summer Arts Festival. He was writing to request new tubes. But he also shared a story about this feeder.

He wrote, "We bought a feeder from you two at a show in Omaha a few years ago and I got some replacement tubes from you I think maybe year before last. We have it down here in Arizona now. The hummers love it, though they don't share well. A little story on the feeder, its popular with the birds and also with guests who remark on its' individuality. A few years ago during our first winter down here we attracted a little female Anna's Hummingbird whom we called Anna (aren't we creative) No other bird has been attached to this feeder like her so I still call it Anna's feeder. She sat on top of a bush maybe 4 feet away from it for the entire winter...I mean everyday, most of the day!! She was so stingy with it, others learned to feed when she was driving some interloper away. Sometimes if the tubes needed refilling she would come to us as we came out of the house and hover about six inches from our faces. Kinda frightening at first but we got used to it and it seemed she wanted fresh food because if I refilled the tubes she would drink while I'll was doing it. We spent the summer in Nebraska that year, returned in the fall, hung the feeder and she was back within a few hours!"

He included a picture of the feeder and amazingly enough, we remember this feeder and we remember meeting them in Omaha. It is so satisfying to know that he has been using this feeder since he purchased it in 2009 and it is still feeding hummingbirds in 2013 and he is still enjoying owning it. That's a darn good return on investment! Thanks, Jeff, for allowing us to share your story.

Hummingbird fact for today: The female hummer will build her nest before she looks for a suitable male mate for breeding.
