Abstract

1. INTRODUCTION
Flint & Franson (2009) comment on our recent paper about influenza A virus in wild mallards (Anas platyrhynchos; Latorre-Margalef et al. 2009). They acknowledge the quality of our data and analyses, but think that our interpretation of the results is incomplete. One can break down their comments into two parts: (i) the issue of assumed causality in our Discussion and (ii) the alternative hypothesis suggested by Flint and Franson, according to which body condition and immune status affect the likelihood of acquiring influenza A infection (rather than the latter affecting the former).
2. CAUSALITY
It is important to stress that the data in our study come from a large and long-term surveillance scheme carried out at Ottenby Bird Observatory in southeast Sweden since 2002. For our paper we analysed [...]
