Supplementary material for "Food availability affects parental anti-predator behaviour in red kites"
<p><strong>Abstract</strong></p> <p>Parental investment theory proposes two non-mutually exclusive hypotheses to explain variation in anti-predator behaviour in relation to the age of offspring: the “reproductive value of offspring” hypothesis and the “harm to offspring” hypothesis. The relative importance of the two factors underlying the hypotheses, reproductive value and harm, may change depending on environmental conditions such as food availability. To test the relative importance of the two hypotheses under different food conditions, we conducted a supplementary feeding experiment in red kite (<em>Milvus milvus</em>) breeding pairs and used a live eagle owl (<em>Bubo bubo</em>) as decoy nest predator to trigger anti-predator behaviour. We used time-to-capture in mist nets mounted next to the decoy predator as proxy for mobbing intensity. Under natural food conditions we found a nearly constant mobbing intensity throughout the entire nestling period. However, under food-enhanced conditions mobbing intensity was reduced in parents with young nestlings and increased in parents with old nestlings. These results suggest greater importance of the “reproductive value of offspring” hypothesis in situations of favourable food availability. Moreover, mobbing intensity depended on brood size and weather conditions. The results suggest that parental anti-predator investment increases with the reproductive value of the brood under favourable breeding conditions, but that this pattern is adjusted to the current context, including the vulnerability of the brood and environmental conditions.</p>
Experimental reduction of haemosporidian infection affects maternal reproductive investment, parental behaviour, and offspring condition
<p>When hosts have a long coevolutionary history with their parasites, fitness costs of chronic infection have often been assumed to be negligible. Yet, experimental manipulation of infections sometimes reveals effects of parasites on their hosts, particularly during reproduction. Whether these effects translate into fitness costs remains unclear. Here, we present the results of an experimental study conducted in a free-ranging population of red-winged blackbirds (<em>Agelaius</em> <em>phoeniceus</em>) naturally experiencing a high prevalence of haemosporidian infections, with > 95% of breeding adults infected with parasites from one or more haemosporidian genus. To assess effects of infection during reproduction, we manipulated adult red-winged blackbird females' parasite burden by administering an anti-haemosporidian medication before onset of egg-laying. Experimental reduction of infection resulted in significant benefits to mothers and their offspring. Medicated females laid heavier clutches, invested more in incubation and provisioning behaviour, and produced more fledglings than control females. Nestlings of medicated females had higher haematocrit, higher blood glucose, and lower reactive oxygen metabolites than nestlings of control females. Overall, our results provide evidence that, even in a species with a long history of high prevalence of infection, parasites can lead to decreased maternal investment and offspring quality, substantially reducing fitness.</p>

A neural substrate for negative affect dictates female parental behaviour.
<p># Abstract</p> <p>Parental behaviours are essential to secure survival and wellbeing of newborns. Concomitantly, parenting also limits negative affective states in adults, which emerge when the coping with neonatal distress becomes a challenge. Whether neural circuits that process negative affect orchestrate components of parental behaviours remains, however, unknown. Here, we identify functional and transcriptional signatures of parental behaviours in neurons of the negative emotion center lateral habenula receiving bed nucleus of the stria terminalis innervation (BNSTLHb). Calcium imaging and optogenetic manipulations reveal that LHb neurons of virgin female mice increase their activity in response to pup distress vocalization and are necessary for pup calls-driven aversive behaviours. Accordingly, LHb activity rises during the retrieval of a pup to a nest, a behaviour worsened by optogenetic LHb inactivation. Intersectional cell identification and transcriptional profiling associates the BNSTLHb neuronal population to parental behaviours and outlines gene expression in female virgins that is similar to mothers but divergent from non-parental virgin male mice. Accordingly, optogenetic activation and inactivation of the BNST-LHb pathway maximizes and suppresses, respectively, the parental behaviour. Finally, tracking and manipulating single BNSTLHb cell activity demonstrates specificity of this neuronal subset for encoding negative affect and pup retrieval, but not sociability amongst conspecifics. Thus, BNSTLHb cells are operational for female parenting, demonstrating that a negative affect neural circuit processes newborn distress signals and limits them through female parenting.</p> <p> </p> <p># Files available to generate figures.</p> <p>- Fastq Files : Raw reads output</p> <p>Alignment of sequenced reads to the mouse genome (GRCm38) and filtered gene–barcode matrices were realized by running Cell Ranger Single-Cell Software Suite v5.0.1 (10X Genomics).</p> <p>The cell ranger count function was used to generate filtered gene/cell expression UMI corrected matrices by selecting probable nuclei and removing empty lipid droplets.</p> <p>Command line use for cell ranger /opt/cellranger-5.0.1/cellranger count --id=MAc --transcriptome=/refgenome/refdata-gex-mm10-2020-A --libraries=library.csv --expect-cells=2000 --include-introns --localcores=20 --localmem=32</p> <p>MAc_S1_L001_R1_001.fastq.gz<br> MAc_S1_L001_R2_001.fastq.gz<br> MBc_S1_L001_R1_001.fastq.gz<br> MBc_S1_L001_R2_001.fastq.gz<br> MCc_S1_L001_R1_001.fastq.gz<br> MCc_S1_L001_R2_001.fastq.gz</p> <p><br> - src.src R script to reproduce analysis.<br> - source.src R source script containing useful functions.</p> <p>- singlecell_countmatrix.tsv.gz: is a count matrix in tab-separated format.

Data from: "Green incubation": avian offspring benefit from aromatic nest herbs through improved parental incubation behaviour
Development of avian embryos requires thermal energy, usually from parents. Parents may however trades off catering for embryonic requirements against their own need to forage through intermittent incubation. This dynamically adjusted behaviour can be affected by properties of the nest. Here we experimentally show a novel mechanism by which parents, through incorporation of aromatic herbs into nests, effectively modify their incubation behaviour to the benefit of their offspring. Our study species, the European starling, includes in its nest aromatic herbs which promote offspring fitness. We provided wild starlings with artificial nests including or excluding the typically selected fresh herbs and found strong support for our prediction of facilitated incubation. Herb effects were not explained by thermal changes of the nests per se, but by modified parental behaviours. Egg temperatures and nest attendance were higher in herb than herbless nests, egg temperatures dropped less frequently below critical thresholds, and parents started their active day earlier. These effects were dynamic over time and particularly strong during early incubation. Incubation period was shorter in herb nests, and nestlings were heavier one week after hatching. Aromatic herbs hence influenced incubation in beneficial ways for offspring, possibly through pharmacological effects on incubating parents.
Light affects parental provisioning behaviour in a cavity-nesting Passerine
Nocturnal bird species possess special adaptations to maximise visual efficiency under low light levels. However, some typically diurnal species also experience low-light environments. For example, cavity-nesting Passerines raise broods in dark cavities and search for food in light-abundant surroundings. It is not clear whether they possess special adaptations for low light vision or breed in cavities at the expense of impaired parental care. In this study, we tested whether light conditions affect the provisioning efficiency of great tits. We experimentally tested how the level of natural and artificially increased illumination inside nest boxes affects parental feeding duration, frequency and timing. We monitored 15-hours of provisioning activity of great tit parents when nestlings were day 7 post hatch. We used traditional "dark" nest boxes and "bright" nest boxes with increased illumination obtained by using semi-transparent plastic windows. The duration of single feedings were, on average, shorter in brightened nest boxes compared to dark ones. This difference tended to be higher early in the morning and in the evening, when the illumination in dark nest boxes was the lowest. Nest box type, however, did not influence feeding frequency or times of the onset and the end of feeding. Our findings provide new evidence for impaired efficiency of parental care due to lowered light conditions. Further research is needed to test whether prolonged feeding duration has negative effects on adult time budgets and nestling energy expenditures.
