Bald Faced Hornet Nest


Large Bald Faced Hornet nest in a tree with some nice bird calls in the background. These are dangerous hornets and they typically build their nests in trees in the wild and near houses so if one accidentally disturbs them while mowing or trimming trees you won't outrun them. The worker hornets here are diligently making the nest even bigger. When found away from any human habitation like this nest its best just to leave them alone as they are in fact quite beneficial by preying on other harmful insects - all in the balance of Nature. Interestingly, if you are quiet you can film them quite closely as here with a cell phone - they have guard hornets posted who are always on the lookout for anything threatening so best to give these nest a wide berth.

Dolichovespula maculata is a eusocial wasp of the cosmopolitan family Vespidae. Its colloquial names include the bald-faced hornet, bald hornet, white-faced hornet, white-tailed hornet, blackjacket, and bull wasp. This species is a yellowjacket wasp, not a true hornet (genus Vespa). Colonies contain 400 to 700 workers, the largest recorded colony size in its genus, Dolichovespula. It builds a characteristic hanging paper nest. Workers aggressively defend their nest by repeatedly stinging invaders.

Dolichovespula maculata is distributed throughout the United States and Southern Canada, but is most common in the southeastern United States. Males in this species are haploid and females are diploid. Worker females can therefore lay eggs which develop into males. Matricide might occur after sufficient workers have been raised and queen-destined eggs have been laid, in order to give workers a reproductive advantage. The sting hurts intensely when first stung and will get a bump but in a couple hours it will not be there.
Baldfaced hornets are distinguished from other yellowjackets by their white and black coloring. It has a white or "baldfaced" head, which is the source of its colloquial namesake. These wasps also have three white stripes at the end of their bodies. They are notably larger than other species of Dolichovespula, as adults average about 19 millimetres (0.75 in) in length. Queen and worker wasps have similar morphologies. However, workers are covered by small hairs while the queen remains hairless. Queens are always larger than workers in their colonies, though size distributions can vary in different nests and workers in one colony might be as large as a queen in a different one.

D. maculata create egg-shaped, paper nests up to 360 millimetres (14 in) in diameter and 580 millimetres (23 in) in length. Nests are layered hexagonal combs covered by a mottled gray paper envelope. Bald-Faced Hornets create this paper envelope by collecting and chewing naturally occurring fibers. The wood fiber mixes with their saliva to become a pulpy substance that they can then form into place.

Northern Flicker Woodpecker Calling and Drumming



Male Northern Flicker woodpecker calls and drums to attract a female to the Screech Owl nest box he has claimed as a nest site. He is a gorgeous yellow-shafted variety common to eastern North America with a call similar to a Pileated Woodpecker, but weaker and higher pitched.  The call ringing through the forest almost brings to mind the sounds of a tropical jungle.
This brown woodpecker flashes bright colors under the wings and tail when it flies. Its ringing calls and short bursts of drumming can be heard in spring almost throughout North America. Two very different-looking forms -- Yellow-shafted Flicker in the east and north, and Red-shafted Flicker in the west -- were once considered separate species.

Yellow Jackets Nest and Swarm


Yellow Jackets building a Nest. Big Yellow Jacket gets upset with one of the smaller workers building the nest and dispenses some punishment which sets all of the Yellow Jackets swarming. I noticed the Yellow Jackets building a new nest just 4 feet off the ground under a tree branch and left the camera running for 30 minutes so these Yellow Jackets managed to get upset all by themselves. Does not take much to set them off. This particular kind of nest is quite dangerous because its in a place where one would bump into it mowing around the trees. I planned to leave it in place for a few days to film its rapid growth, but a Black Bear ate it the next night. A nice little snack for them. Filmed in the Great Smoky Mountains.

Cute White Footed Mouse and Nest

:


White Footed Mouse family have a luxury house in an underground water meter high in the Great Smoky Mountains. Cute little fellow - if you watch closely you'll see him rub noses with Mrs Mouse who I'm pretty sure has babies in the downy nest. I gave them a little bird seed and left them undisturbed - will keep an eye on them.

House Sparrows Feeding Babies in Nest


House Sparrow couple feeding two babies in a nest in an old Purple Martin house grown over by tree branches on a trip north. This is not Purple Martin habitat so they are not displacing them, but like the House Wren they are tenacious defenders of their cavity nests.  Introduced from Europe in the 19th century the House Sparrow is now a common bird in many urban areas. This nice clean, attractive couple display the energy and dedicated work ethic of caring for their young. If you watch closely you will see a fecal sac removed to keep the nest clean and some housekeeping done as the adult enter the nest and tidy up.

Blue Jay Couple Gathering Nest Material



Mating Blue Jay couple building a nest are gathering material over two days. Both parents participate in gathering material and building the nest. They are very slow and picky about what they gather and appear to give the subject great deliberation. Notice especially on the first half of the video that they each have different kinds of materials. They both give a barely audible contact chirp while they gather and are very careful about revealing the location of their nest. Typically flying a circuitous route back to the nesting site in case a predator is watching. They are extremely intelligent backyard birds.

Owlet Swallows a Whole Lizard

As I continue to go over the video from this seasons nest box camera I come up with jewels like this. The largest owlet was barely a week old on April 17th when it attempted to swallow an entire lizard that the parents dropped into the nest box. By this time both parents would immediately start hunting after dark dropping large amounts of food, mostly lizards, into the nest box. There intent is to come back shortly and tear up the lizards for the owlets, but one couldn't wait even though it could barely see. There seemed to be an inexhaustible supply of lizards this spring partly due no doubt to the fact that it was a very warm winter. It also speaks to the lack of pesticides in the backyard - I know that's a hard call for some, but Palmetto Bugs and Mole Crickets and such along with lizards make up a large portion of their diet at nesting time. Note that the mother Screech Owl comes to the rescue of the little guy near the end to help him with the lizard.

The Power of a Perch - Nest Box Experiences Part 3

You can enhance the chances of attracting Screech Owls to your nest box  by using bird feeding stations in your yard that make good perches for the owls and other creatures.  We use two Gardman USA Wild Bird Feeding Kits that are very good as a bird feeding station and absolutely outstanding as sturdy perches. The only weakness is the pole that comes with the kit is in 4 sections and its not particularly strong or long-lasting, but we use 7ft pieces of copper plumbing pipe that makes the total kit quite strong and attractive. Its the hardware that comes with the kit that is the best part. It has held up quite well. Its sometimes hard to find this exact  kit but for now its still available through Amazon. Gardman makes another slightly different Deluxe feeding station that is  probably just as good.

We had a serious problem with squirrels climbing all over the feeders, but found the Woodlink 18" Squirrel Baffle did the trick in stopping them from ruining bird watching. The YouTube video below is a test we did a few months ago. This type of baffle could also be used to keep squirrels out of your Screech Owl box is it was on a sturdy galvanized metal pole. You may be able to find one for use on 4x4 wood posts, but if it doesn't swivel like this one the squirrels may well defeat it.



                                                              
These are the exact products used in the video above. We don't link unless we own and use it!!

Flyways to perch and nestbox

The second Gardman unit is used as a perch just for the owl box and creates a safe flyway pattern between heavy brush cover and the nest box,  making the box more attractive to the owls as well as serving as a great hunting perch at night. It is very common to see them sitting there and catching large bugs and lizards in the backyard grass which is pesticide free. It is also where they would meet during mating season and was no doubt a plus in selling the "house" to the female screech owl. Its all about neighborhood, neighborhood neighborhood.

Of course the twin perches will be generally attractive to all birds. Its always a rush to see a majestic Red-Shouldered Hawk stop by and perch in the yard.  Occasionally they will take out a Dove sitting on the perch or a snake from the yard. Hawks by day and owls by night!




Dragonfly Perching

The perch is often used as a hunting perch in the daytime by insects such as large wasps and dragonflies. In this picture you can see the owl box in the distance in the lower right. Dragonflies eat an amazing amount of insects alleviating the need for heavy pesticide use.

Dragonflies use the highest tip for a daytime hunting perch. Perches will attract more birds and are especially attractive to Screech Owls.
