List Five Birds That You've Observed While They Were In, On, Or At Their Nests

Barn swallow
Great blue heron
Golden eagle (through a powerful scope)
Green heron
Mourning dove

Red-winged Blackbird (very vigorous defenders of their nesting area!)
American Robin
Mourning Dove
Great Blue Heron

I like this one!

Gray Hawk
Cooper's Hawk
Osprey (what can I say, raptors are big and their nests are easy to spot!)
Bewick's Wren
Cordilleran Flycatcher (seeing it at its nest really helped with the ID here!)

American Robin
Carolina Chickadee
House Sparrow
Cooper's Hawk (unfortunately an unsuccessfull pair)

Chihuahuan raven
Elegant trogon
Elf owl
Mountain chickadee
Rose-throated becard

tropics, does it count if I spent half an hour watching the becard nest and never actually saw the becard?

Lorax: I'm sorry that you missed it. Did you hear it? That would count. It's an amazing nest for such a small bird.

emerald green hummingbird(it visits me when Iam deadheading flowers)
small brown bird w/long curvered beak has a nest under the deck stairs & comes very close to me when Iam sitting out on patio
many cardinals, but one is almost golden
robin red breast who follows behind me when I hand till any soil gobbling up bugs & sadly my earthworms
I see & hear others, but not good at i.d.
Do you ever contemplate "bird flu" and had sad it would be if we lost all birds?

Cliff swallow
House wren
Red-tailed hawk
Rock wren
Tree swallow

Blackcollared barbet
Crested barbet
Southern red bishop
House sparrow
Cape weaver

American Robin
Common Barn Swallow
Osprey
Canada Goose (Darn near lost a toe cause of it!)
Mallard Duck

Not five, but at this moment I have a nest of mourning doves in my window box outside my kitchen. They are almost ready to fly and will give me the dove eye when I'm cooking. The cat has been quite interested in watching them too, they learned she can't get to them.

Cactus wren (in a large cholla cactus)
Curve-billed thrasher (likewise)
Costa's hummingbird (in a Tombstone rose vine)
Cooper's hawk (in a tall pine tree)
Eared grebe (floating nest on a shallow lake)

Osprey - multiples
Robin
house finch
mallard
barn swallow

American Robin
Great Horned Owl
Pileated Woodpecker
Herring Gull (of course carrying a stick overhead while doing banding at a rookery)
Ruby-throated Hummingbird

(Today I showed a Polish business associate a nest, in Connecticut. We had been watching this hummingbird zinging back and forth to and from a spruce bough. It took us oh, about a nanosecond to check under the branch and find the lichen-covered nest. My Polish friend was totally bonkers. No hummers in Poland.)

A pair of Mockingbirds which are nesting in a tree in my backyard at the moment and vigorously defending their territory from everything from squirrels to crows.

A wren's (sorry don't know what kind) nest complete with hatchlings in a fern on a friend's front porch.

A Carolina wren (we think) started building a nest on top of a column on the front porch. My sweetie knocked it down because it was making a mess. I chased the sweetie away with threats and imprecations. The bird came back and built the whole thing within a day. Very interesting to watch one so close.
