Jennifer Border

Senior Research Ecologist

Jenni works as a postdoc researcher on a NERC-funded project entitled 'Explaining and Predicting the Migration and Phenology of European-African Migratory Birds'.  This project is undertaken in collaboration with Durham University.  For more details please see here

Interests & Responsibilities

Jenni's current research focuses on European-African migratory birds.  The project aims to:

1) Collate an extensive set of tracking, ringing and observation data on trans-Saharan migrant songbirds
2) Parameterise, build and test spatial models of songbird migration
3) Use these models to explore how region-specific population changes in European-African migrants over recent decades are linked to changes in migratory journeys and how migration behaviour changes under different environmental conditions.

In her previous four years as a Spatial Ecologist at BTO Jenni worked on a wide range of projects, primarily centred around large datasets and modelling distributions and trends.  These included predictive modelling of bats' spatial sensivity to urbanisation and opportunities for birds and bats from habitat restoration; assessing gaps in survey coverage at a UK level for birds, bats, butterflies and plants; investigating the likelihood of non-native species invading the UK; modelling breeding phenology in farmland birds; modelling spatio-temporal change in UK bird trends; determining cuckoo use of protected areas and determining drivers of change in moorland breeding bird populations.

Prior to joining BTO Jenni was involved in research such as determining population limitations in a lowland grassland migrant (the whinchat), tagging and tracking seabirds and eradication of the invasive myna birds in the Seychelles.

Jenni is also also a member of the BTO seminar committee, organising the fortnightly seminar series.  If interested in giving a seminar please email seminars [at]
