Second Nesting Attempts by Allen's Hummingbirds

While most birds are working on their first nests of spring, the Allen's hummingbirds in our yard are on round two.

This nest has two newly laid eggs. It isn't the best constructed nest, but it is in a shaded and protected location. The novice female hasn't been sitting on the nest as much as the more experienced moms.

The female in the front yard has been the only mother to successfully bring two chicks to fledging. See her first chicks just before they flew. Now she's back on the same nest with two new eggs. Last year her second nest was in a different location and nearly lost to the sun.

The nest on the patio successfully produced one fledgling. (The second chick died a day after our big wind storm. Amazingly the survivor lived for a week beside it's desiccated sibling. We considered trying to remove the dead chick, but the location of the nest made that difficult. The survivor was developed enough to try to escape and there was nothing, but cement, 12 ft beneath the nest. Ultimately, it was the right choice; the surviving chick is flying around the yard.)

In the canyon part of the yard, we discovered a nest with two healthy chicks just after they had hatched. The two chicks are just starting to develop their elongated hummingbird beaks. You can just see the second chick's beak at the left side of the nest. These two should be flying in a week and a half to two weeks.

So far this year all of the nests have been in our native Catalina cherry and its mainland relative the hollyleaf cherry. Only the patio nest was not in these specific plants. That is our key to having so many hummingbird nests in our yard–native shrubs. The growing pattern of the plants match the needs of the hummingbirds. Native plants also flower when the hummingbird mothers need food.

If you are keeping track, in 2019 so far, we've had :

• 8 nests
• one pair and three singleton Allen's hummingbird chicks successfully fledged - total of 5
• 2 chicks currently in a nest
• 4 eggs still being incubated 

Rescuing hummingbird chicks

Allen's Hummingbird Builds Summer Nest

Look what's taking form in the garden.

Yesterday I spotted one of our Allen's hummingbird females working diligently on a new nest. June seems a little late, but the on-again off-again summer weather may have spurred this little female to try a brood before the heat of July and August.

Typically, we see hummingbirds nesting February through May. 
 

In March, these two Allen's hummingbird chicks took their first flights just a day after this photo. (A nest a few years ago in Jan /Feb.)

This female is obviously availing herself of the natural cotton in our "Nature's Nest" natural nesting material. She has been weaving the beige cotton fibers with spider webbing and decorating it with pieces of leaves and sticks. The natural cotton plant fiber is moisture resistant and helps keep chicks cool even as the weather heats up. 

The nesting material has become rather frayed at the edges as a variety of bird beaks have plucked and tugged at it. We've seen not only Allen's and Ann's hummingbirds, but lesser goldfinches and oak titmice using the Nature's Nest.

Interestingly, this new female Allen's is building her nest in the same low branches of the photinia that one of our long-term resident females used to build in all the time. Hummy raised several broods in nests built in this same location. That female hummingbird passed away or moved on in 2005. One of her daughters, "A," held the territory for five years, but for the last two summers no one female has held the territory or nested in this location. 

I can't help but wonder: Is this one of A's daughters or granddaughters? Or is this location and the upturn of these branches just ideal for Allen's hummingbirds to nest in?

Rescuing Baby Hummingbirds

Spring is definitely here. Baby birds and nests are everywhere. Currently, there are two active Allen's hummingbird nests in the yard. (A-1 has two chicks and DR-2 still has eggs. The third nest, D-1, was abandoned after the female broke one of the eggs.)

The other day I had a comment from someone saying that they had a baby hummingbird and they didn't know if they should leave it alone or call for a rescue group to pick it up.

The baby Allen's hummingbird pictured here is still downy and can't fly. It is out of the nest, but its mother is still taking care of it. The chick calls to the mother and she only appears for short bursts to feed it. It does not need to be rescued.

Here are some key points to remember regarding baby birds.

1. No one can take better care of a baby bird than its parent. Young birds with feathers usually have NOT fallen out of a nest, but are learning to fly. Some species like hummingbirds and California towhees leave the nest before they can really use their wings. They hang out in shrubs for a few days learning to fly. BEFORE you try to save a baby bird, watch it for a while. There probably is a parent bringing it food. This spring the Bewick's wrens brought one of their young fledglings to the yard like it was day care. The young bird could barely fly. It poked around the patio and the planters all day. In the evening the parents came and took it home. This went on for 3 or 4 days. A few years ago a young crow spent about a week in the yard. It couldn't fly. Parents and siblings brought it food and usually, a family member was stationed to watch over it. In both cases, we did nothing but provide a safe place. Most birds are good parents. Rarely, do they abandon a chick.
   
2. Sometimes baby birds do fall out of a nest. The first step is to PUT THEM BACK. Most birds do not have a sense of smell. You are not going to scare off the parent.
3. Older chicks may push a younger or weaker sibling or out of the nest. If this is the case, there may be a reason. Perhaps the parent only has resources for one chick. In some cases, cowbirds will lay their eggs in other species' nests. The cowbird chick will push out the owner's chicks. This seldom happens in Southern California. I did have a situation in 2008 when very hot weather caused an older hummingbird chick to push its younger sibling out of the nest. In the photo, you can see the mother, "P" is perched on the nest. The larger chick, Pop, is in the nest. The smaller one, Peep, is on a branch beneath the nest. These chicks were only about a week from fledging, so they were mostly developed. We replaced the smaller chick, but it was pushed out again. We made a small replacement nest, put it about 8 inches from the original nest and the mother bird continued to raise both chicks successfully.
4. Parent birds typically leave their chicks while they go off to get food. Sometimes they stay away from the nest so that they don't attract predators. But parent birds come back to their offspring. A few years ago a friend had a fledgling CA towhee get stuck in her garage over night. She was concerned she was going to have to call a rescue person. In the morning we opened up the garage. The parents waiting outside, calling for the chick. It took a few hours, but the parent birds lured the chick out of the garage. Family reunited.

I can't say it strongly enough. The best way to rescue a baby bird is to reunite it with its parent.

Hard Working Single Mom - Allen’s hummingbirds

The yard is filled with young birds just out of the nest. The California towhees have dropped off the first youngster of the year and gone off to raise a second brood. When I go out to pull a few weeds in my neglected vegetable garden, I usually have a companion. The young towhee keeps me in sight as it prowls the undergrowth for insects and seeds. I’m not sure if I am company or a second pair of eyes to watch for the Cooper’s hawk.

Unlike the towhees where both parents participate in feeding and raising the young, hummingbird females are all on their own. We don’t have many hummingbirds at our feeders, what we have is a nursery area–five or six Allen's hummingbird females nesting in specifically drawn territories. We seldom see males. The girls don’t want flashy breeding guys drawing attention to the location, so they typically chase them away. Occasionally a young male, usually hatched here, will be allowed to stay for a while. But as he reaches maturity, he is told in no uncertain terms that this area is off limits. Hummingbird mothers work hard to lay, incubate and then feed their young. They don’t want a male attracting attention and risking the lives of vulnerable nestlings.

Right now, the busiest kids in the yard are the four Allen’s hummingbirds that have fledged in the last two weeks. This year I have found four nesting females: A, C, D and F. A hatched here in the yard in 2005. When her mother disappeared, she seemed to inherit her mother’s territory. Last year she had trials as a mother, A’s nesting in 2007, this year she laid early and had her kids out of the nest before the jays came marauding.

A’s first brood fledged on 4/1 and 4/2. Typically, hummingbird eggs are laid a day or so apart and frequently the youngsters will be staggered in their maturity.

D made her first nest high in a grevillia tree, but it was destroyed in one of our winter storms. Her second nest was lower in a protected area and her two youngsters fledged on April 14, 2008. Here you can see one sitting on the edge of the nest and the slightly older one sitting about six inches from the nest. They both fluttered their wings furiously, exercising their flight muscles, buzzing a few inches at a time.

In the second picture the younger fledgling has its wings spread wide as it tries to learn to fly.

Mom kept returning all day to feed them and offer support. The older youngster flew off by midday and between 5 and 6 PM the younger one took flight as well. Yesterday, the two new kids were quite noticeable as D took them to visit the various feeders in the yard. There was quite a flutter when A’s youngsters realized there were two new hungry beaks at the feeder.

Today the fledglings are pretty much on their own. You can see them exploring different plants in the yard, trying to get the hang of what has nectar and what does not.

Meanwhile, just two days after her job with one brood of youngsters is done, D is building a new nest to start the process all over again. She has moved to a small ficus bush and started the nest‘s button foundation. She will continue to build it up with plant and animal fibers, spider webbing and bits of different materials.

What about C and F ? C’s youngsters should fledge in the next 4 to 5 days. And then there is F. I’m not sure what is going on in her nest. It’s a mystery. There were hatchlings, but they never seemed to get bigger. She’s still on the nest. Stay tuned, we’ll solve it.
