The tropical pewee or southern tropical pewee (Contopus cinereus) is a small passerine bird in the tyrant flycatcher family. It breeds from southern Mexico and Trinidad south to Bolivia and Argentina. The taxon punensis, found in south-western Ecuador and western Peru, is usually included as a subspecies of the tropical pewee, but it has been suggested it should be considered a separate species, the Tumbes pewee (Contopus punensis) . This pewee is found at the edges of forests and cultivated areas with tall trees. The nest is a small open saucer of fibre and grasses, lined with grass and decorated with lichen on its exterior. It is placed in a tree fork or on a branch. The female builds the nest and incubates the typical clutch of two creamy-white eggs, which are marked with red-brown spots at the larger end, for 15–16 days to hatching. The tropical pewee is 14 cm long and weighs 12 g. The upperparts are dark brown or grey with a blackish crown and two whitish wing bars. The throat and centre of the breast are whitish, the abdomen is pale yellow, and the sides of the flanks and breast are grey-brown. There are large variation in the overall darkness of the plumage, and especially the nominate subspecies from south-eastern Brazil and adjacent parts of Paraguay and Argentina can be very dark, almost approaching the blackish pewee in colour. The beak is short, with a black upper mandible and orange lower mandible. Sexes are similar. Tropical pewees perch on a high watchpoint from which they sally forth to catch flying insects, returning to the same exposed perch. This is a conspicuous species, with a trilled threeee call, or a sharp weet. There are, however, some geographical variations in its voice. It will defend the nest aggressively against species as large as a great kiskadee.

A DNA barcode is a short, standardised stretch of genes that works like a fingerprint — enough to tell one species from another. Below is the molecular trace Contopus cinereus has left across the world's sequence archives.
At a glance
★ the standard DNA barcode for this group — the short region actually read to tell this species apart. The rest are extra genes sequenced along the way.
The complete instruction manual Contopus cinereus carries — its genome. We read it from three angles — how big it is, how the DNA is packed into chromosomes, and how completely it has been sequenced — and explain how to read each value as you go.
Genome sizehow big the whole instruction manual is
Measured in base pairs (bp) — the individual letters of DNA (human ≈ 3.2 Gb, a bacterium a few million). The chart places this genome on a logarithmic scale — each step to the right is ten times bigger — among reference organisms. Across species a bigger genome loosely tracks with larger cells, slower growth and lower-energy lifestyles (powered flight favours small genomes) — yet it does not imply more genes or a more advanced organism (the long-standing C-value paradox).
How far back this lineage goes — and how we know. Everything here is measured in Ma, short for “mega-annum”: millions of years ago. The chart reads left to right like a calendar of the Earth, from the deep past on the left to today at the right edgetop to bottom like a core drilled through the Earth, from the deep past at the top down to today at the bottom.

When this lineage existed
How to read this: the coloured strip along the bottomdown the left is the geological calendar — the standard epochs (Pliocene, Pleistocene…) every museum uses, shown so you can see which chapter of Earth's history this lineage lived in. This lineage is a young one, so the strip is zoomed in to epochs — the finer subdivisions inside a period. The orange marker is the DNA clock: DNA accumulates mutations at a roughly steady rate, so comparing this species' DNA with its relatives estimates when the lineage split off — independently of any fossil.

Where the DNA of Contopus cinereus was picked up in samples of water, soil or air — nobody saw the organism, only its DNA left behind. A trace is a clue that the species was near, not a confirmed sighting.

How strong is each trace?
Modelled climatemodelled
How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
