However, the resolution of the DNA-DNA hybridization technique used by Sibley & Ahlquist was not sufficient to properly resolve the relationships in this group, and indeed it appears as if the Charadriiformes consititute a single large and very distinctive lineage of modern birds of their own.

Molecular studies such as DNA-DNA hybridization ( Sibley & Ahlquist, 1990 ) and sequence analyses fail to resolve the relationships of grebes properly due to insufficient resolution in the former and long-branch attraction in the latter.

Initial mtDNA cytochrome b sequence analysis ( Mariaux & Braun 1996 ) agreed with earlier morphological ( Cracraft 1981 ) and DNA-DNA hybridization ( Sibley & Ahlquist 1990 ) studies insofar as that the oilbird and the frogmouths seemed rather distinct.

Phylogenetic analyses have shown that mimids are most closely related to starlings ( Sibley & Monroe 1990, Zuccon et al.

They are sometimes united with the starlings in the Sturnidae as a tribe Mimini as proposed by Sibley & Monroe ( 1990 ).

DNA-DNA hybridization and RAG-1 sequence data places it as a wader related to the jacanas ( Sibley & Ahlquist 1990, Paton et al.

Sibley & Monroe ( 1990 ) included the mimids in the family and demoted the starlings to tribe rank, as Sturnini.

However, the grouping of Sibley & Monroe ( besides leaving the subfamily rank vacant ) is overly coarse due to methodological drawbacks of their DNA-DNA hybridization technique and most of their proposed revisions of taxonomic rank have not been accepted ( see for example Ciconiiformes ).

On the other hand, DNA-DNA hybridization ( Sibley & Ahlquist 1990 ) placed the white-eyes closer to Sylvia.

Since 1990 ( Sibley & Ahlquist 1990 ), molecular data has been added to aid the efforts of discovering the parrotbills ' true relationships.

Perhaps the " high-water mark " of phenetics were the DNA-DNA hybridization studies by Charles G. Sibley, Jon E. Ahlquist and Burt L. Monroe Jr., from which resulted the 1990 Sibley-Ahlquist taxonomy for birds.

The use of techniques such as DNA-DNA hybridization to study evolutionary relationships was pioneered by Charles Sibley and Jon Edward Ahlquist resulting in what is called the Sibley-Ahlquist taxonomy.

In their pioneering DNA-DNA hybridisation work, Sibley and Ahlquist found that the genetic difference between the eared-nightjars and the typical nightjars was, in fact, greater than that between the typical nightjars and the nighthawks of the New World.

American ornithologists Charles Sibley and Jon Ahlquist recognised the close relationship between woodswallows and the butcherbirds in 1985, and combined them into a Cracticini clade, which became the family Artamidae.

Over the decades, many ornithologists suggested that members of the order were in fact more closely related to other groups ( reviewed by Olson 1985, Sibley and Ahlquist 1990 ).

Sibley and Ahlquist furthermore removed button-quails ( Turnicidae ) from the Gruifomes based on large DNA-DNA hybridization distances to other supposed Gruiformes.

The Sibley-Ahlquist taxonomy is a bird taxonomy proposed by Charles Sibley and Jon Edward Ahlquist.

In 1988 Sibley and Jon Ahlquist were awarded the Daniel Giraud Elliot Medal from the National Academy of Sciences.

Partly due to personality conflicts, Sibley had few long-term collaborations with other scientists, with the notable exception of Jon Ahlquist.

Ornithologists Charles Sibley and Jon Ahlquist recognised the close relationship between the woodswallows and the butcherbirds and relatives in 1985, and combined them into a Cracticini clade, which later became the family Artamidae.

According to the famous DNA hybridization study into avian phylogenetic relationships by Sibley and Ahlquist, the split of the Procellariiformes into the four families occurred around 30 million years ago ; a fossil bone often attributed to the order, described as the genus Tytthostonyx, has been found in rocks dating around the Cretaceous – Paleogene boundary ( 70-60 mya ), but the remains are too incomplete for placement within the Procellariiformes to be certain.

Charles Sibley and Jon Ahlquist, pioneers of the technique, used DNA-DNA hybridization to examine the phylogenetic relationships of avians ( the Sibley-Ahlquist taxonomy ) and primates.

Thus some authorities place them in the Ciconiiformes with the storks and herons ; Sibley and Monroe ( 1990 ) even considered them a subfamily of the stork family.

The Bearded Reedling tended to appear close to larks in phylogenies based on e. g. DNA-DNA hybridization ( Sibley & Ahlquist 1990 ), or on mtDNA cytochrome b and nDNA c-myc exon 3, RAG-1 and myoglobin intron 2 sequence data ( Ericson & Johansson 2003 ).
