Temperature and aridity determine body size conformity to Bergmann's rule independent of latitudinal differences in a tropical environment.
Nwaogu CJ, Tieleman BI, Bitrus K, Cresswell W. Nwaogu CJ, et al. J Ornithol. 2018;159(4):1053-1062. doi: 10.1007/s10336-018-1574-8. Epub 2018 Jun 27. J Ornithol. 2018. PMID: 30956931 Free PMC article.
We test whether variation in temperature and aridity determine avian body size conformity to Bergmann's rule independent of latitude differences, using the ubiquitous Common Bulbul Pycnonotus barbatus, along a West African environmental gradient. We trapped 538 bird …

The most responsive birds to audio lures were gregarious species (e.g. Pycnonotus barbatus, Dryoscopus cubla, Prionops plumatus, Phoeniculus purpureus, Turdoides jardineii and Lamprotornis chalybaeus) and the aggressive Dicrurus adsimilis and Acridotheres tristis. . …

Varying prevalence (16.7-100%) of anti-T. gondii antibodies were recorded across 10 of 35 wild bird species; 2 (28.6) of 7 African thrush (Turdus pelios), 2 (33.3) of 6 speckled mouse bird (Colius striatus), 1 (20.0%) of 5 speckled fronted weaver (Sporopipes frontalis), 1 (33.3%) …

Interestingly, NiBAP has recorded about 75% of the bird species known from Nigeria in only about 50% of Nigeria's total surface area, including 39 nationally threatened species. The Common Bulbul Pycnonotus barbatus, Laughing Dove Spilopelia senegalensis, and Grey-b …

Geographic variation in baseline innate immune function does not follow variation in aridity along a tropical environmental gradient.
Nwaogu CJ, Cresswell W, Tieleman BI. Nwaogu CJ, et al. Sci Rep. 2020 Apr 3;10(1):5909. doi: 10.1038/s41598-020-62806-1. Sci Rep. 2020. PMID: 32246110 Free PMC article.
We sampled blood and measured five innate immune indices from 286 Common Bulbuls Pycnonotus barbatus between 6 and 13N. We sampled in the dry season; we resampled the first location (Jos) also as the last sample location to test temporal change in immune function. . …

A fruit diet rather than invertebrate diet maintains a robust innate immunity in an omnivorous tropical songbird.
Nwaogu CJ, Galema A, Cresswell W, Dietz MW, Tieleman BI. Nwaogu CJ, et al. J Anim Ecol. 2020 Mar;89(3):867-883. doi: 10.1111/1365-2656.13152. Epub 2020 Jan 3. J Anim Ecol. 2020. PMID: 31764994 Free PMC article.
We performed a balanced parallel and crossover design experiment with omnivorous common bulbuls Pycnonotus barbatus in out-door aviaries in Nigeria. We fed 40 wild-caught bulbuls ad libitum on fruits or invertebrates for 24 weeks, switching half of each group betwee …

Seasonal differences in baseline innate immune function are better explained by environment than annual cycle stage in a year-round breeding tropical songbird.
Nwaogu CJ, Cresswell W, Versteegh MA, Tieleman BI. Nwaogu CJ, et al. J Anim Ecol. 2019 Apr;88(4):537-553. doi: 10.1111/1365-2656.12948. Epub 2019 Feb 6. J Anim Ecol. 2019. PMID: 30659607 Free PMC article.
Here, we effectively decouple seasonal environmental variation from annual cycle stage effects by exploiting cross-seasonal breeding and moult in the tropical Common Bulbul Pycnonotus barbatus. We test how annual cycle stage interacts with a key seasonal environment …
