83:992011-04-30Albert Lea Lake, Albert LeaFreeborn(record #2011-013, vote 1-6). This record was initially Accepted, vote 5-2. At the 28 August 2011 meeting, a majority decided to reconsider this record. These very experienced observers may have seen a Neotropic Cormorant, but sufficient details are lacking to effectively eliminate all other small cormorants. While the possibility of these birds being small cormorants other than a Neotropic is extremely remote, the Committee has rejected other records based on this same reasoning. Consequently, neither bird was Accepted. Not Accepted

This is possibly the same individual that was seen at this location the previous year (The Loon 92:3). Remarkably, the state's purported (still under MOURC review) eighth Neotropic Cormorant joined this bird on 19 July 2020 and both were present until 21 August 2020. The latest date that two birds were seen simultaneously was 21 August 2020. One of these two birds lingered until 20 October 2020 although the identity of which one was not undetermined. Accepted

This bird was joined by an immature (see below) which was first observed on 11 June 2021. Apparently, this immature bird had been seen at least several weeks prior to 11 June 2021 and possibly as early as early May 2021 until the observer realized there were two different birds when both the immature and the adult were observed together. Both individuals were seen together sporadically at least until 21 September. One of these two individuals lingered until 5 October 2021 although the age of that bird was not documented. Accepted
