There was a time when I thought each bird species had its own individual song. Then I found out that there was this vocalization called a ‘call,’ so I thought each bird species had its own individual song (but just the males) and individual call. Bird communication is a complex and evolving science.

Or, Pygmy leaf-folding frogs, Afrixalus brachycnemis, from Tanzania, tiny climbing frogs who lay their eggs in leaves and then fold the leaves over them for protection, sealing the nest with secretions. There is a large family of frogs, Bufonidae, that includes most of the warty, hoppy creatures we think of as toads.

It’s not often that we have the opportunity to glimpse the home life of albatrosses, nor of any seabird species. Where does the female Emperor Penguin go after she has produced that one egg and handed it over to the male for incubation? Technology to the rescue! What about incubation shifts?

Artists rendition of Inkayacu paracasensis There are 17 living species of penguins, which make up their own Linnean family (Spheniscidae), which is the only family in the order Sphenisciformes. Penguins are flightless, but some species locomote over long distances on antarctic ice to travel between breeding grounds and the sea.

At the very least appreciated for their hard-shell adaptation, the way they quietly survive in ponds, rivers, oceans, islands, forests, even, for a few species, deserts, and, if you are of a certain age, their cultural depiction as ninja warriors. Or that tortoises and terrapins are considered part of the turtle family.

Even the Latin species name soror (“sister”) indicates the similarity to another pitta species (blue-naped). The eBird description of the Small Niltava starts with the surprisingly dull statement that “size distinguishes this species from other niltavas” Who would have thought.

Gisela Kaplan has written a book about the species, and how they seem unperturbed by humans: “It’s one of their most successful defense strategies. When these birds breed, this can lead to highly cringeworthy announcements, for example from Adelaide Zoo : “We have egg-citing news!” This is what killed James Dean.

The vast majority of the 10,000+ living species of birds are passerines, and the vast majority of those have a similar system of breeding: Mom and dad bird make a nest and share parental responsibilities roughly equally, if not identically. There are variations on that theme, of course. Even the non-passerines often follow this pattern.

A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. One North American species I am very familiar with is the Cassin’s Auklet , which ranges from the end of the Aleutian Islands to California.

I have written about the interesting sex life of these jacanas a few times already (short version: female mates with male, lays a bunch of eggs for him to incubate and raise the chicks, leaves him, finds another male, repeat). Apparently, after a male first mates with a female, he throws out the first one or two eggs she lays in their nest.
