While I love gardening and swimming in the summer, watching the foliage change in the fall, and skiing and snowshoeing in the winter, there's nothing that makes me feel alive quite like the first warm days of spring. A scent calls to me, and I simply must get outside to enjoy the unique aromas of the season.

This corner of New Hampshire was buried under nearly 150 inches of snow this past winter, a record for us. Now, each day I count how many stones in the garden wall are newly visible, which trees are starting to bud out, and how much more brown earth is visible near the dirty piles of snow. Those piles are still high, but they are melting and spring is definitely here.

In one patch of earth, I notice a small flock of juncos feeding. Since they weren't here during the long winter months, I assume they've journeyed from somewhere south of us. They bustle about, finding a few stray seeds scattered by the blue jays, which roil the feeders by suddenly taking off. A robin hops along, searching for something tasty in the ground.

On my walk, I'm serenaded along the way by the red-winged blackbirds. First comes a little bell-like sound and then the wings open, flashing the distinctive red patch, and the head bends down and forward for the big "scree." Three males are dueling furiously. First one sings out and the moment he's finished, a second starts up, followed immediately by a third. Their perches are only a few feet apart. Will they really nest so closely or will one remain victorious while the others leave for new territories?

The common grackles have returned, too. Their brilliant yellow eyes stand out from their lustrous blue-black coats, shining iridescently in the sunlight. Clustering together on a tall tree, they have long and raucous discussions about what? Their recent flights north? The quality of the sunflower seeds at my feeders (duly brought in each night now that the bears are astir)? The depth of snow on the still-frozen swamp? Perhaps they, like me, are simply delighting in the warm spring air.

Nearby, great blue heron couples are choosing their nesting sites. Two of last year's nests are already taken. Refurbished a bit, they're now ready and a heron stands guard over each while the mates are off doing some fishing. Perhaps the first eggs have already been laid. A third nest is being looked over by a pair in mating plumage. They stand on the nest and peer down at it, appearing to ask: What do you think? Will this one do? I call that nest "faraway" because it's off by itself, a short distance from the remaining nests used last summer.

In another tree, two birds stand near a small pile of sticks. I watch while one flies off to a pine and pulls some foliage to spruce up their new home. When it returns, the mate calls out to him before taking the bough and carefully trying it here and then there until just the perfect spot is found. Slowly, the nest takes shape.

Although two more of last year's nests stand empty, the heron activity is far from over. A fifth pair has also chosen a new site for their nest. They've placed few shortish branches in a crotch where two limbs meet the trunk of a long-dead pine. The herons stand one above the other and peer out in different directions over the swamp. I love their looks: plumage flying off the back of the heads, bold orange bills contrasting with the blue-gray feathers.

Nearby I spot yet another pair. They stand side by side in a tree to the south of the others, looking off over the swamp. Last year's five mating couples produced fourteen young; I can hardly wait to see how many six pairs will produce this season.

Meanwhile, one small area of the swamp has freed itself of ice and snow. The opening starts at the beavers' spillway and runs out for perhaps 20 feet. I scan it for ducks, but see none. I know some have returned to the larger lakes and ponds in the surrounding areas. Perhaps soon the swamp will have enough open water to tempt a mallard pair or a beautiful hooded merganser and his mate to fly in for a rest. Or maybe a wood duck couple will discover the nesting box high in the tree on the west side of the swamp.

It's spring. They'll be here soon.
