Abstract: In this paper we describe the ectoparasitic lice (Insecta: Phthiraptera) found on 5 species of seabirds (magnificent frigatebird Fregata magnificens; great frigatebird Fregata minor; Nazca booby Sula granti; blue-footed booby Sula nebouxii; and red-footed booby Sula sula) on the Galapagos Archipelago. We found 9 species of ectoparasitic lice: 5 species of Pectinopygus ischnocerans, 1 infesting each host; 2 species of Colpocephalum amblyceran lice, 1 on each frigatebird species; and 2… 
Lineage sorting in multihost parasites: Eidmanniella albescens and Fregatiella aurifasciata on seabirds from the Galapagos Islands
TLDR
It is found that host species identity was the only factor explaining the patterns of genetic structure in both parasites, and a revision of the taxonomy of these louse species is needed.
The Chewing Lice of Brown Booby (Sula leucogaster) in Southeastern Brazil
TLDR
In the years 2018 and 2019, 4 marine animal rehabilitation centers located in Rio de Janeiro and São Paulo, Brazil received live birds and carcasses of Sula leucogaster, and lice of 2 different species were collected.
Parasite diversity associated with African penguins (Spheniscus demersus) and the effect of host and environmental factors
TLDR
It is concluded that parasite infestations are structured and that penguin chicks at mainland colonies are more susceptible to parasite infestation during spring, compared with autumn/winter.
Sex-dependent changes in the louse abundance of red-footed falcons (Falco vespertinus)
TLDR
Investigating how static and dynamic traits of red-footed falcons interplay with the dynamics of their louse subpopulations during breeding and how they affect the colonisation of new hosts by lice found that sex-biased infestation levels likely arise due to parasite preferences in the nestlings and host behavioural processes in the adult falcons.
Sex interacts with age-dependent change in the abundance of lice-infesting Amur Falcons (Falco amurensis)
TLDR
The effect of Amur Falcons’ sex, age and body size on the abundance of their lice at a migratory stopover site, where the falcons’ habitat use and behaviour are more homogeneous across sex and age categories than during the breeding season is investigated.
Host sympatry and body size influence parasite straggling rate in a highly connected multihost, multiparasite system
TLDR
This study supports the general perception that successful colonization of a novel host is extremely rare, as it found only one nymph of a straggling species, which may indicate successful reproduction.
Slow motion extinction: inbreeding, introgression, and loss in the critically endangered mangrove finch (Camarhynchus heliobates)
TLDR
Current genetic diversity of the last remnant population is far below levels 100 years ago, with only about half of the allelic diversity retained, and current genetic diversity is close to levels in the Fernandina population that went extinct by the 1970s.
Parasites of seabirds: A survey of effects and ecological implications
The eldest sibling is the lousiest in an obligate brood-reducer seabird
TLDR
Investigating how infestation by Eidmanniella pellucida varies in relation to the age, the order of birth and the hatching date of chicks suggested that lice would prefer the chick that is more likely to survive and highlights the adaptive strategies of lice according to the ecology of their hosts.
Colonization of Parasites and Vectors
TLDR
Examples of natural and anthropogenic colonization of the Galapagos Islands by parasites and vectors are explored, focusing on one or more case studies that best represent the diversity of colonization mechanisms that has shaped parasite distribution in the archipelago.

An annotated checklist of parasitic lice (Insecta: Phthiraptera) from the Galápagos Islands.
TLDR
A host-parasite list, and a list of hosts which breed in the Galápagos Islands but without lice recorded from them are included, and four lectotypes from the Kellogg Collection are formally designate.
Comprehensive investigation of ectoparasite community and abundance across life history stages of avian host
TLDR
It is suggested that ectoparasites might synchronize their life cycles to those of their hosts and have important implications for evolution of parasite-specific host defenses.
Comparative ecology of Neotropical bird lice (Insecta: Phthiraptera)
TLDR
The bulk of variation in louse load was among host species nested within genera, although some variation occurred at higher taxonomic levels.
EFFECTS OF HOST SOCIALITY ON ECTOPARASITE POPULATION BIOLOGY
TLDR
This work studies parasites that differed greatly in life history in the context of the Galapagos hawk's variably cooperative mating system to demonstrate significant differences in a suite of population responses between these louse suborders in thecontext of host sociality.
Vertical Transmission of Feather Lice Between Adult Blackbirds Turdus merula and Their Nestlings: A Lousy Perspective

TLDR
Examination of the transmission of 4 species of feather lice from parent blackbirds to their nestlings in an English population addressed questions formulated from the perspective of the lice, predicting that lice might aggregate on female blackbirds, which undertake more brooding, to increase their chance of transmission to nestlings.
Ectoparasites reduce long-term survival of their avian host
TLDR
It is suggested that future studies of ectoparasitism should consider the parasites’ effect on annual survival of adult hosts and suggest that all birds in the population were at potential risk of suffering parasitism and the resulting reductions in survivorship.
Multiple cophylogenetic analyses reveal frequent cospeciation between pelecaniform birds and Pectinopygus lice.
TLDR
Perfect congruence between phylogenies is not found in this association, probably as a result of occasional host switching by the lice, thus emphasizing the need for improved cophylogenetic methodologies.
Influence of host ecology and morphology on the diversity of Neotropical bird lice
TLDR
This study proposes a specific functional hypothesis in which preening damages lice by exerting a shearing force between the overhang and the tip of the lower mandible, and is the first to suggest a parasite-control function of such a detailed component of bill morphology across species.
Parasite-specific variation and the extent of male-biased parasitism; an example with a South African rodent and ectoparasitic arthropods
TLDR
The results suggest that the extent of a gender-biased pattern of parasite infestation of the same host may not only involve host-related mechanisms but also depends on biological features of a particular parasite species.
Dust-ruffling: A simple method for quantifying ectoparasite loads of live birds
TLDR
A simple, accurate method for quantifying the ectoparasite loads of live birds in the field, which required less equipment and was more accurate and efficient than previously described methods, as it is shown by comparing the method to other popular approaches.
