Sentinels in Saltator atricollis (Passeriformes: Emberizidae) [PDF]
Revista Brasileira de Biologia, 2001 I studied the existence of sentinels in Saltator atricollis in a 'campo-cerrado' (Brazilian savanna) during the breeding seasons of 1994-95 and 1995-96. Groups of this species consisted of two to seven birds (N = 25). Sentinels were present (mean ± sd) 62% ± 9% of the time, and most sentinel bouts lasted from less than one to six minutes (although in ...

The earliest Tyrannida (Aves, Passeriformes), from the Oligocene of France [PDF]
Scientific Reports, 2020 AbstractPasseriformes is the most diverse bird order. Nevertheless, passerines have a remarkably poor early fossil record. In addition, high osteological homoplasy across passerines makes partial specimens difficult to systematically assign precisely.

Further Evidence for Paraphyly of the Formicariidae (Passeriformes) [PDF]
The Condor, 2005 Abstract The historical relationships of ground antbirds and their relatives have long been unresolved. Here, I present a phylogenetic analysis of ground antbird (Formicariidae) relationships based on DNA sequence data from the cytochrome-b and ND2 genes.

SYSTEMATICS AND EVOLUTION IN THE TITYRINAE (PASSERIFORMES: TYRANNOIDEA) [PDF]
The Auk, 2007 AbstractWe tested the monophyly and determined the phylogenetic relationships of the seven genera (Laniisoma, Laniocera, Iodopleura, Pachyramphus, Schiffornis, Tityra, and Xenopsaris) and 27 of the 31 recognized species of the subfamily Tityrinae using complete gene sequence data from the mitochondrial gene NADH dehydrogenase subunit 2.

Two passeriform birds (Aves: Passeriformes) from the Middle Miocene of Austria [PDF]
PalZ, 2021 AbstractTwo newly discovered specimens of passerine birds—an isolated sternum and an associated skeleton—from the upper Middle Miocene (ca. 12 Ma) are the oldest representatives of Passeriformes from Austria. Although the condition of the specimens prevents their accurate identification, they provide further clues on the morphological diversity of the ...

Cytogenetic Evidence Clarifies the Phylogeny of the Family Rhynchocyclidae (Aves: Passeriformes)
Cells, 2021 The phylogenetic position and taxonomic status of Rhynchocyclidae (Aves: Passeriformes) have been the subject of debate since their first description. In most models, Rhynchocyclidae represents a subfamily-level taxon placed within the Tyrant Flycatchers
