Psittacopasseres

Psittacopasseres is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Psittacopasseres rather than just read about it. In short: Psittacopasseres is a taxon of birds consisting of the Passeriformes (passerines, a large group of perching birds) and Psittaciformes (parrots). Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising passerines, psittacines and Falconiformes.

Key takeaways

Psittacopasseres belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Psittacopasseres to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Psittacopasseres from memory before moving on to harder problems.

Reference excerpt

Psittacopasseres is a taxon of birds consisting of the Passeriformes (passerines, a large group of perching birds) and Psittaciformes (parrots). Per Ericson and colleagues, in analysing genomic DNA, revealed a lineage comprising passerines, psittacines and Falconiformes. The group was proposed following an alignment of nuclear intron sequences by Shannon Hackett et al. in 2008. It was formally named as Psittacopasserae in a 2011 Nature Communications article by Alexander Suh and other authors working with Jürgen Schmitz's group, based on genetic analysis of the insertion of retroposons into the genomes of key avian lineages over the course of evolution during the Mesozoic Era. This clade was defined in the PhyloCode by George Sangster and colleagues in 2022 as the least inclusive crown clade containing Psittacus erithacus and Passer domesticus.

Significance in the evolution of birdsong Passerines are renowned as songbirds (technically this word refers to a clade of passerines), and parrots share a capacity for vocal learning. Thus it is possible that vocal learning, and the corresponding variety of song, was present in a psittacopasseran ancestor.

Worked examples

Example 1 — a first encounter with Psittacopasseres

Start with the simplest possible case. Write down what Psittacopasseres claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Psittacopasseres before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Psittacopasseres ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Psittacopasseres

In research: Psittacopasseres appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Psittacopasseres in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Psittacopasseres is common in secondary-school and first-year university syllabi. It links to neighbouring topics Neognathae, so understanding it makes those chapters shorter.
In everyday life: Look for Psittacopasseres outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
