At the beginning of the essay Doyles has a very admirable and interested tone when he describes the "hummingbird’s heart [that]is a lot of the hummingbird. Joyas voladoras, flying jewels, the first white explorers in the Americas called them, and the white men had never seen such creatures, for hummingbirds came into the world only in the Americas, nowhere else in the universe"(1),emphasizing how wonderful the life of these birds much like humans is rare is unique.
Not long after the tone changes to more sober tone as Doyle mention that their "hearts [can]sludge nearly to a halt, barely beating, and if they are not soon warmed, if they do not soon find that which is sweet, their hearts grow cold, and they cease to be"(3)this implies that without the contant want and retrievable of excitement and need in ones life the more deprived it will be.

Doyles uses compare and contrast for the lifestyles of humans to the hearts of animals expression that "You can brick up your heart as stout and tight and hard and cold and impregnable as you possibly can and down it comes in an instant"(6),he compares the physical heart of an animal to the emotions and mentality of humans.
Doyles uses cause and effect in this essay by describing how the positives of animals heart can effect it negatively,when he describes how "The price of their ambition is a life closer to death; they suffer more heart attacks and aneurysms and ruptures than any other living creature".
Doyle also uses description to provide information on the hearts of the animals that are being symbolized throughout the essay,he informs the audience that "There are perhaps ten thousand blue whales in the world, living in every ocean on earth, and of the largest animal who ever lived we know nearly nothing. But we know this: the animals with the largest hearts in the world generally travel in pairs, and their penetrating moaning cries, their piercing yearning tongue, can be heard underwater for miles and miles"(5)this creates a sense of community and need for more relatioships/connections.

The use of metaphor to compare a wall to a heart describing that"You can brick up your heart as stout and tight and hard and cold and impregnable as you possibly can and down it comes in an instant"(6) emphasizes the fragility of peoples emotions and need to be more open to change.
The use of repetition at the beginning of each sentence,"You burn out. You fry the machine. You melt the engine." provides a sense of responsibility for the audiences actions.
The uses symbolism of being naked to being vulnerable stating that "Perhaps we could not bear to be so naked, for fear of a constantly harrowed heart"(6)illustrates that people are afraid of being vulnerable and taking risks is not a sustainable nor wanted lifestyle.
Doyle uses simile to describe to ways of life"You can spend them slowly, like a tortoise and live to be two hundred years old, or you can spend them fast, like a hummingbird, and live to be two years old."(5)presenting two different ways of living for two animals helps provide two paths for the audiences life.
The use of simile to compare the heart of blue whale to large spaces stating that"It’s as big as a room. It is a room, with four chambers. A child could walk around it, head high, bending only to step through the valves. The valves are as big as the swinging doors in a saloon...unimaginable puberty and then it essentially disappears from human ken, for next to nothing is known of the the mating habits, travel patterns, diet, social life, language, social structure, diseases, spirituality, wars, stories, despairs and arts of the blue whale"(5)this creates mystery and diversity in the way of living and how it can defer for everyone and not everything can be already known about that life.

Doyles states a fact  about the humming to the reader saying that "Each one visits a thousand flowers a day. They can dive at sixty miles an hour. They can fly backwards. They can fly more than five hundred miles without pausing to rest"(3)it appeals logically and helps emphasize the quickness and consistent lifestyle of they have.
Doyle also creates emotional association to the lives of theses animals to those of people " The price of their ambition is a life closer to death; they suffer more heart attacks and aneurysms and ruptures than any other living creature. It’s expensive to fly. You burn out. You fry the machine. You melt the engine"(3)the constant use of the word "you" creates a connection with the animal.
Doyle credibility is shown through describing his vivid memories " the brush of your mother’s papery ancient hand in the thicket of your hair, the memory of your father’s voice early in the morning echoing from the kitchen where he is making pancakes for his children"(6)by making his experiences and making himself vulnerable to his emotions he appeals to the audience.

In his essay "Joyas Voladoras"(2012),Brian Doyle asserts that humans need to experience a life that is emotionally satisfying.He supports this claim by comparing the hearts of animals to the decisions and lifestyles a person can decide for themselves and tries to create a sense security in vulnerability.His purpose is to inspire a need for a fulling life for people in order to have less regret when a life can suddenly end without meeting goals and standards in life.He establishes a passionate and confrontational tone in the essay for the misguided and uncertain audience in need for an elevated living expectation.
