Planning a nestbox temperature manipulation experiment in birds? We’ve just published a preprint that may be useful! 🪺🪶
We review 46 studies and also share our own blue tit pilot experiment from Wytham Woods, highlighting some very real practical challenges doi.org/10.32942/X25387
Spring is gaining momentum across Scotland. 🌱
Cumulative budburst across the transect has now passed 40%, driven by a surge of activity at our northern sites in recent days. While the North is waking up, the South continues to lead the way in terms of first leaf emergence.
#Phenology #Spring2026
The first week of the 2026 field season is underway, and Storm Dave has provided a chilly – but atmospheric – start. ❄️🏔
63 blue tit nests initiated, so far, with 4 lined. Looking like a later start for us compared to elsewhere in the UK/Western Europe.
#phenology
The first egg for the 13th year of data collection along the Phenoweb Transect was laid on 12th April 2026! Looking like we’re in for a fairly ‘average‘ year up here in Scotland, with nest building and budburst progressing slightly slower than in 2025, especially in the North of the transect🪺🌳
New preprint (part of a programme to understand resilience of the tritrophic tree-insect-bird system to varying climate). We (led by @siennarattigan.bsky.social - her MBiol project) show how temperature in development can carry-over to affect timing at later stages

In our new paper, published yesterday, we use the long-term data set of Wytham Woods to show that great tits have maintained stable temperature at breeding despite the almost 2ºC increase in Spring temperature. w.
