This appears to be a bald-faced hornet (Dolichovespula maculata). These individuals and the nest was observed hanging over Lake Temagami in Ontario, Canada. It was a pleasant August day. The nest actually hung over the water -- I was standing in the lake to take this picture.

Nest

A suspended Pyramidal Nest- house for meditation, tea, smoke and deep, deep sleep.
This nest was built in the rafters of 1 of the bird observation blinds at Great Swamp. I was expecting to observe birds from the blind, not in the blind! But I saw some droppings on the floor, looked up, & saw these. I'm pretty sure they are Eastern Phoebes, since those love nesting in human structures, & there was an adult hanging around right outside the blind. The adult didn't seem agitated -- I thought it was just going about its business catching flies, until I discovered the nest. And the nestlings were quiet as a mouse while we were there. However, as I lifted the camera towards the nest to take the picture, they started to gape for me. Apparently it's a generic reflex towards anything approaching. We vacated the premises thereafter to let the parents get back to parenting.

The hamerkop (Scopus umbretta), is a medium-sized wading bird. It is the only living species in the genus Scopus and the family Scopidae. The shape of its head with a long bill and crest at the back is reminiscent of a hammer, which has given this species its name. It is found in Africa, Madagascar to Arabia, living in a wide variety of wetlands, including estuaries, lakesides, fish ponds, riverbanks and rocky coasts. The hamerkop, which is a sedentary bird that often show local movements, is not globally threatened and is locally abundant in Africa and Madagascar.
The hamerkop was first described by the French zoologist Mathurin Jacques Brisson in 1760 in his landmark Ornithologia, published two years after the tenth edition of Carl Linnaeus' Systema Naturae. Brisson's work was later incorporated by Linnaeus into the 12th edition of the Systema Naturae. Brisson's names for bird genera were widely adopted by the ornithological community despite the fact that he did not use Linnaeus' binomial system. The International Commission on Zoological Nomenclature (ICZN) ruled in 1911 that Brisson's genera were available under the International Code of Zoological Nomenclature, so Brisson is considered to be the genus authority for the hamerkop. The specific name umbretta was given to the hamerkop in 1789 by the German naturalist Johann Friedrich Gmelin. The generic name, Scopus, is derived from the Ancient Greek skia for shadow. The specific name umbretta is modified from the Latin for umber or dark brown.[8]
The hamerkop is sufficiently distinct to be placed in its own family, although the relationships of this species to other families has been a longstanding mystery. The hamerkop is usually included in the Ciconiiformes, but might be closer to the Pelecaniformes. Recent studies have found that its closest relatives are the pelicans and shoebill.
The hamerkop is the only living member of its family, but one extinct species is known from the fossil record. Scopus xenopus was described by ornithologist Storrs Olson in 1984 from Pliocene deposits found in South Africa.
The hamerkop is also known as the hammerkop, hammerkopf, hammerhead, hammerhead stork, umbrette, umber bird, tufted umber, or anvilhead.
There are two subspecies currently recognised. The widespread nominate race S. u. umbretta, and the smaller of West African S. u. minor, described by George Latimer Bates in 1931. Two other subspecies have been proposed. S. u. bannermani of south west Kenya is usually lumped with the nominate race. It has been suggested that birds in Madagascar may be distinct, in which case they would be placed in the subspecies S. u. tenuirostris. That proposed subspecies was described by Austin L. Rand in 1936. It has also been suggested that birds near the Kavango River in Namibia may be distinct, but no formal description has been made.

September 24, 2016 - The following text comes from Galapagos Conservation Trust website: "The Galapagos flightless cormorant is an endemic species to Galapagos and is not only the heaviest cormorant species, but also the one which cannot fly out of 29 species. As the name suggests, they cannot fly away and are therefore confined to the lava shoreline and beaches of Isabela and Fernandina. The adults are black on top and dark brown underneath with bright turquoise eyes. They have stunted wings that are one third the size of the wingspan they would require to fly. They have four webbed toes (like all members of the cormorant family) and the females tend to be smaller than the males. Natural selection led to the species no longer having functional wings as they had very few land predators, and individuals that were better suited to swimming were more successful in passing on their genes.
Currently there are around 1,000 breeding pairs of flightless cormorants on Isabela and Fernandina. Although their wings are stunted, they are used for balance when the cormorant jumps from rock to rock along the coast. As their wings don’t produce very much oil, they have lost some of their waterproofing so after a dive they can be seen to hold their wings out in order for them to dry.
Their diet consists mainly of eels and octopus, which they reach by diving deep to the ocean floor. Unlike penguins, they do not ‘fly’ underwater, but tuck in their wings and kick with their powerful hind legs, using their flexible necks to spear octopus and fish from inside small refuges in the reefs and rocks. On the surface they sit very low in the water, with only their necks visible from a distance.
Couples perform a strange and unique courtship dance that involves them intertwining their necks whilst twirling in a tight circle. The mated pair then makes a nest a few metres from the sea out of seaweed, flotsam and jetsam.
Most eggs are laid between May and October, which are the coldest months, resulting in an abundance of marine food and less heat stress on the hatchlings. The eggs are incubated for 35 days until they hatch, after which the parents take turns to feed the chicks. Eventually the male is left to care for the chick and the female starts a new breeding cycle, which can happen up to three times in one season. When the chicks become adults, they develop the trademark blue eyes"

Foreground: dummy nest. Background: real nest.
I was not able to extract all of the materials from the real nest intact. The twigs and other materials were packed tightly under and around the nest cup.
I cleaned out two nest boxes used by a pair of House Wrens in summer 2009. My Birdcam photographed a wren carrying a stick into one of them.

Not sure exactly what this is but was found in garage in October. Size between golf ball and cricket ball. Was attached to the thin stick with hole pointing downwards but moved to take the picture. At first thought it was an ordinary wasps' nest where the colony had died out almost immediately after starting (they grow much larger). But after looking at other images on this site could be some sort of solitary wasp. This is Scottish Highlands and I haven't noticed hornets around.
This hummingbird chose to nest in a bush just in front of my office door. At first, it would fly away every time someone opened the door. Now it's getting used to the people.

The nest of a common wild species found here in the Scottish countryside. It migrates from more densely populated environments, commonly purchases all the essentials required to survive in this inhospitable place on a Friday night and, like a bower bird, decorates its nest with the detritus of its weekend of mind-numbing excesses.

Memo: Bag it and take it home.
This is a replica of the Great Nest of Vermilion, Ohio. It is a Bald Eagles nest measuring 12 feet tall by 8.5 feet wide across its flattened top. It stood 81 feet from the ground in the leaning top of a Shellbark Hickory tree. It weighed 2,000 lbs and took 35 years to get to this size. It is on display at the Carlisle Reservation of the Lorain County Metroparks in LaGrange, Ohio.
Hornet nest makes from the shredded wood and saliva, so they look like wrapped up of paper. Such paper nests can be installed on the ground or trees, also in the shelter.
A walk in the garden can reveal hidden secrets that is in front of you but not visible to the naked eye. Today was one of those moments when me and my niece spotted two leaves stitched beautifully. Only then I realized this amazing craftmanship could have been done only by a Tailorbird which is a daily visitor but surprised no one spotted it until date. The nest was brilliantly made with intrecacies of threading, precision and care that defies logic, just proves that humans have to learn from nature for eternity!
I'm not sure what little bird made this nest. It was beautifully woven from dried grasses and moss and hanging from a low diagonal limb. Very small so I suspect one of the vireos or small wrens. It was during winter so no birds using it that I could see.
